discussed  in the forward-looking statements. Uncertainties that may cause these
differences  include,  but  are  not  limited  to:
     -    Fluctuation  in  the  demand  for  our  products;
     -    The  level  of  market  acceptance  of  our  products;
     -    The  development  of technically superior products by our competitors;
     -    Our  ability  to  sell  our  products  at  a  profitable  price;  and
     -    Our  ability  to  fund  our  operations  through  positive  cash flow.

For  further  discussion  regarding  these and other uncertainties, see "Factors
That  May  Affect  Future  Results."


OVERVIEW
- --------

     We  are  engaged  in  designing,  manufacturing,  and  marketing  various
optoelectronic  products,  ultraviolet  (UV)  detectors and related products and
optical  components.  For  several  years, we also received significant revenues
from  research and development services projects sponsored by various government
agencies.  In fiscal 1998, we shifted our emphasis from research and development
to product development, with the intent to eventually manufacture and market our
own  proprietary products. We received no revenues from research and development
activity  in  fiscal  2001  and do not expect any revenues from this activity in
fiscal  2002.

     For  the  last  several  years  our goal has been to manufacture and market
products/components  based  on  our  technology developments. We have focused on
dense  wavelength  division  multiplexer  (DWDM)  components  for  fiber  optic
communications  and  gallium  nitride  (GaN)  based  ultraviolet  (UV) detectors
comprising  components  and  integrated detector/electronic/display packages for
both  industrial  and  consumer applications. The consumer application is in the
form  of  a  wristwatch  marketed  under  the  name  SunUVWatch(R).

     We  chose  these two product areas because we believe they have significant
potential  markets and because we have expertise and/or patent positions related
to them. In addition to these products, we manufacture custom optics for various
industrial  customers.

     The  telecommunications industry continues to experience reduced demand for
capital  goods  such  as  our  DWDM components. We expect this period of reduced
demand  to  continue for several months. This weakness continues to put downward
pressure  on  component  pricing,  margins  and profits. The presence of several
manufacturers  of  DWDMs  pursuing  this  soft  market  has  also added downward
pressure  to  component  pricing.  Aggressive pricing and declining requests for
quotes  will  likely  have a negative impact on our financial performance for at
least  the  next  few  fiscal  quarters.

     Environmental  performance  is  a  key test factor for qualification of our
products  under  industry  standards  as  promulgated  by  Telcordia. During the
quarter  ended  December  31,  2001,  we  continued  to make improvements in the
environmental  performance  of  our DWDMs. However, we have not yet begun formal
testing  of  our  DWDM  components  for  Telcordia  compliance.


                                        6

     We  have  resolved  most  of  problems related to mechanical and electronic
aspects of this product that previously delayed full release, we have launched a
promotional  campaign,  and  we have an initial set of distributors in place. We
believe  that  awareness of the risks of excessive UV exposure continues to grow
and  that  this  awareness  should  support demand for this product. However, we
still  face  the  significant  challenges  of creating consumer awareness of the
SunUVWatch(R)'s usefulness in measuring UV exposure and increasing production at
our  offshore  assembler.


RESULTS  OF  OPERATIONS
- -----------------------

REVENUES

     Revenues  for the quarter ended December 31, 2001, were $49,089, reflecting
a 83% decrease from the comparable period in the preceding fiscal year, and were
$570,997  for  the  nine months ended December 31, 2001, an increase of 25% over
the  revenues  for  the  comparable period in the preceding fiscal year. Lack of
demand  for  DWDM components and problems in production that resulted in delayed
shipments  and  cancelled  orders  were  the primary factors contributing to the
decline  in  revenues  during  the  most  recent  fiscal period. The increase in
revenues  for the nine months ended December 31, 2001, was largely the result of
sales  of  our  DWDM  components  during  the  first  quarter  of  fiscal  2002.

COST  OF  SALES

     Cost  of  sales  increased  $289,278  to  $1,026,341  for the quarter ended
December  31,  2001, reflecting a 39% increase over the comparable period in the
preceding  fiscal  year.  For  the  nine months ended December 31, 2001, cost of
sales  increased  $1,173,654  or 67% to $2,926,509 over the comparable period in
the preceding fiscal year. The increases in the cost of sales were the result of
operating with increased production staff and facilities, increased sales during
the  first  quarter,  expansion  of  quality  programs and costs associated with
testing  products  for compliance with certain industry standards. Gross margins
for  sales  were  negative in both periods. The fluctuation in cost of sales and
the  negative  gross margins are influenced by the low unit production and sales
levels  relative  to the capital equipment and personnel committed to production
in  the  early  phases  of  market  introduction  of  our products. We expect to
continue  to  experience  negative  gross  margins  until there is a significant
increase  in  sales  and  production  levels.

RESEARCH  AND  DEVELOPMENT  EXPENSES

     Research  and development expenses increased by $56,746 to $342,224 for the
quarter  ended  December  31,  2001.  This  represents  an  increase of 20% from
research  and  development  expenses  in  the comparable period of the preceding
fiscal  year.  For  the  nine  months  ended  December  31,  2001,  research and
development  expenses  decreased  $98,023 or 11% to $761,116 from the comparable
period  in  the  preceding  fiscal  year.  The increase during the quarter ended
December 31, 2001 reflects the strategic realignment of staff, part of which was
the increase in research and development efforts in GaN based power transistors.
For  the  nine  months  the  decrease  in  research and development expenditures
reflects  increased  commitment to production during the first quarter of fiscal
2002.  We  expect  research  and  development  expenses  to  increase  for  the
foreseeable  future  with  a  gradual  expansion  of  our  research  and product
development  activities.

SELLING,  GENERAL  AND  ADMINISTRATIVE

     Selling, general and administrative expenses decreased $188,458 to $315,842
for  the  quarter  ended  December  31, 2001, reflecting a 37% decrease over the
comparable  period  in  the  preceding  fiscal  year.  For the nine months ended
December  31,  2001,  selling,  general  and  administrative  expenses decreased
$23,604  or  2%  to  $504,300 over the comparable period in the preceding fiscal
year.  The  decrease  for  the  quarter is primarily the result of non-recurring
expenses  related  to  adoption  of  a  shareholders  rights  plan and incentive
compensation  paid  to  management in the quarter ended December 31, 2000. There
were  no  similar  expenses  in  the  quarter  ended  December  31,  2001.

LOSS  FROM  OPERATIONS


                                        7

     The loss from operations was $1,635,318, an increase of $389,422 or 31% for
the  quarter  ended December 31, 2001 over the comparable period in fiscal 2001.
For  the nine months ended December 31, 2001, the loss from operations increased
$936,954 or 27% to $4,379,302 over the comparable period in the preceding fiscal
year.  The  increased loss in the quarter ended December 31, 2001, was primarily
the result of the decline in revenues from the previous fiscal quarter. The lack
of demand for DWDM components and production problems related to DWDM components
were  the  major  factors  contributing  to  this  decline.

OTHER  INCOME  AND  EXPENSE

     Other  income  decreased  $395,743 or 65% to $213,566 for the quarter ended
December  31,  2001,  from  the  comparable  period in fiscal 2001. For the nine
months  ended  December  31,  2001,  other  income  decreased $350,212 or 27% to
$609,309  over the comparable period in the preceding fiscal year. The decreases
for the quarter and for the nine months were due to the combination of a decline
in  the  rate  of  interest earned on short-term investments and a lower average
cash  balance,  as  cash was consumed to fund operations and capital investment.
Interest  rates have continued to decline and we anticipate continuing decreases
in  interest  income as a result of these declines and as a result of the use of
cash  in  operations  and  for  capital  expenditures.

NET  LOSS

     The  net  loss  for the quarter ended December 31, 2001, was $1,422,002 (or
$0.12 per basic and diluted share), an increase of $785,165 or 123% from the net
loss  reported  for  the  same  period in fiscal 2001. For the nine months ended
December  31,  2001, the net loss was $3,431,564 (or $0.29 per basic and diluted
share),  a  40%  increase  over  the  net  loss for the comparable period in the
preceding  fiscal  year. For the quarter, the increased loss was attributable to
the  decline  in  revenues,  the  costs  associated  with  increased  staff  and
facilities,  and  the  decline  in  interest  income.  For the nine months ended
December 31, 2001, the increased loss was attributable to the continued negative
gross  margin on product sales and the costs associated with increased staff and
production  facilities.


LIQUIDITY  AND  CAPITAL  RESOURCES
- ----------------------------------

     APA's  cash  and  cash  equivalents  primarily  consist  of certificates of
deposits,  US Government instruments or commercial paper with maturities of less
than three months. The balance of cash and cash equivalents at December 31, 2001
is  $32,813,014  compared to $21,225,492 at March 31, 2001. The increase in cash
is  primarily  the  result  of  the  maturing  of  short-term  investments.

     Cash  used in operating activities was $2,742,677 for the nine months ended
December  31,  2001,  compared  to  $1,784,083  for the comparable period in the
preceding fiscal year. Our use of cash in operations was primarily the result of
our  operating  loss  and the payment of outstanding accounts payable during the
period.  Our  use  of  cash  was partially offset by non-cash charges related to
depreciation,  amortization,  a  provision  for  obsolete  inventory,  and  the
collection  of  accounts  receivable.

     We  used  net cash of $1,003,243 in investing activities in the nine months
ended  December  31,  2001,  compared  to  $406,448  for  the same period of the
preceding  fiscal  year.  The  funds  were  used  for the purchase of equipment,
facility  repairs  and  leasehold  improvements  that had been deferred in prior
years  and  to  maintain  existing  and  pursue  new  patents  related  to  our
technologies.

     Net  cash  provided  from  financing  activities  in  the nine months ended
December  31, 2001 totaled $15,333,422. The increase was primarily the result of
reclassification  of  $15,759,000  of  short-term  investments  to cash and cash
equivalents  as the time to maturity of these investments shortened to less than
three  months. We used a net of $363,140 for the scheduled reduction of debt and
$92,639  for  the  repurchase  of common stock. We repurchased a total of 43,200
shares at an average cost of $2.14 per share. For the nine months ended December
31,  2000,  net  cash  provided  by financing activities totaled $34,542,410. We
raised  $39,835,156  from  the  sale  of common stock, used $5,033,054 to retire
preferred  stock and used a net of $146,149 for the scheduled reduction of debt.


                                        8

     We anticipate a total of approximately $1.5 million in capital expenditures
in  fiscal  2002,  primarily  for  equipment.  The  majority  of  the  capital
expenditures  relate  to  the  expansion  and  automation  of our production and
research  and  development  facilities.

     We believe we have sufficient funds for operations for at least the next 12
months. Our rate of consumption of cash could change depending upon our level of
research  and  development  activity,  our  level  of  marketing and advertising
activities,  and/or  acquisition  activities.


TRENDS  AND  OUTLOOK
- --------------------

     We  continue  to  experience  performance  issues  related to environmental
specifications in our DWDM products and we are currently working to identify and
remedy  the  design  and/or manufacturing deficiencies that are the cause of the
problems.  Our  industrial GaN products are still under development and have not
been  distributed  in  any quantity that establishes commercial viability. As of
January 31, 2002, we have no order backlog or requests for quotes for any of our
products.  In  addition,  the  current costs of production of our products would
likely  result  in negative gross margins on any order for DWDM components under
current  market  conditions.

     We  are confident in the merit of our DWDM and GaN technologies and believe
that  commercial  viability  can  be  established within the foreseeable future.
However,  we  do  not  anticipate  achieving  profitability  unless and until 1)
production  costs for DWDM's are reduced, the design and manufacturing processes
are  demonstrated  to  repeatedly  produce  components  meeting  the  Telcordia
qualification  requirements,  the demand for these components returns, and 2) we
can  generate  SunUVWatch(R)  unit  sales  at  production  volumes.

FACTORS  THAT  MAY  INFLUENCE  FUTURE  RESULTS
- ----------------------------------------------

     Several  factors  will  influence  our  future  results  including:

UNLESS  WE  GENERATE  SIGNIFICANT  REVENUE  GROWTH,  OUR INCREASING EXPENSES AND
NEGATIVE  CASH  FLOW  WILL  SIGNIFICANTLY  HARM  OUR  FINANCIAL  POSITION.

     We  have not been profitable since fiscal 1990. As of December 31, 2001, we
had  an accumulated deficit of $16.9 million. We will incur operating losses for
the  foreseeable  future,  and  these losses may be substantial. Further, we may
continue  to  experience  negative  operating  cash  flow in the future. We have
funded  our  operations  primarily  through  the  sale  of equity securities and
borrowings.  During  the  last  fiscal quarter, we did not generate any material
revenues  from  the  sale  of  our  DWDM or GaN based product offerings. We have
significant  fixed  expenses  and we expect to continue to incur significant and
increasing  manufacturing,  sales  and  marketing,  product  development  and
administrative  expenses.  As  a  result,  we  will need to generate significant
revenues  while  containing  costs  and  operating expenses if we are to achieve
profitability.

WE  MUST  REDUCE  OUR  COST  OF PRODUCTION IF WE ARE TO ACHIEVE ACCEPTABLE GROSS
- --------------------------------------------------------------------------------
MARGIN  LEVELS.
- ---------------

     From  the  time  we  began  marketing  our  DWDM components in fiscal 1999,
average  selling  prices  for these components have declined and we believe they
will continue to decline. We must continually find means of reducing our cost of
production  if  we are to achieve and maintain acceptable levels of gross margin
on  these  products.  While  we  believe  we  will  be  able  to reduce our DWDM
production  costs  in  the  foreseeable future, our competitors may reduce their
costs  faster and more significantly than we can. Our inability to competitively
reduce  production  costs  could  seriously  harm  our results of operations and
financial  condition.

WE  HAVE  RECENTLY  EXPERIENCED  QUALITY  CONTROL  PROBLEMS

     Manufacturing of our products is a complex and precise process. We recently
experienced  difficulty  in  delivering  DWDM  components  in  line with desired
environmental  specifications  and  have  not yet resolved all the problems that
prevented  us  from  delivering  the  product.


                                        9

WE  MUST  INCREASE  OUR MANUFACTURING CAPACITY OR WE WILL NOT BE ABLE TO DELIVER
OUR  PRODUCTS  TO  OUR  CUSTOMERS  IN  A  TIMELY  MANNER.

     We have limited experience in rapidly increasing our manufacturing capacity
or  in  manufacturing products at high volumes. In order to sell our products in
commercial  volumes and to decrease our costs of production per unit, we will be
required  to  hire,  train  and  manage  additional  manufacturing personnel and
improve  our  production  processes.  There  are  numerous risks associated with
rapidly  increasing  capacity,  including:

     -    Difficulties  in  achieving  adequate  yields  from  new manufacturing
          lines,

     -    Difficulty  maintaining the precision manufacturing processes required
          by  our  products  while  increasing  capacity,

     -    The  inability  to timely procure and install the necessary equipment,
          and

     -    Lack  of  availability  of  qualified  manufacturing  personnel.

     The  expansion  and  automation of our manufacturing facilities and related
capital  expenditures  are  being  made  in  anticipation of a level of customer
orders  that  may  not be realized. If anticipated levels of customer orders are
not  received,  we  will  not  be  able  to  generate positive gross margins and
profitability.

OUR DEPENDENCE ON OUTSIDE MANUFACTURERS MAY RESULT IN PRODUCT DELIVERY DELAYS.

     Some  of  the  components incorporated into our products are purchased from
outside  vendors. If these vendors fail to supply us with components on a timely
basis  or  fail  to  deliver  components  that meet our specifications, we could
experience  significant  delays  in  shipping  our  products.  Any  significant
interruption  or  deficiency  in  the  supply or support of any components could
seriously  harm  our  sales  and  our  relationships  with  our  customers.

OUR PRODUCTS MAY HAVE DEFECTS THAT ARE NOT DETECTED BEFORE DELIVERY TO OUR
CUSTOMERS.

     Some  of  our  products  are  designed  to be deployed in large and complex
optical  networks and must be compatible with other components of the customer's
system,  both  current  and future. In addition, our products are relatively new
and  may  not  operate  as expected over long periods of time. Our customers may
discover  errors  or  defects  in  our  products only after they have been fully
deployed.  If  we  are  unable  to  fix  errors or other problems, we could lose
customers,  lose  revenues,  suffer  damage  to  our brand and reputation, incur
liability  for  repair or replacement of defective parts or damage to customers,
and  lose our ability to attract new customers or achieve market acceptance. Any
of  these factors would negatively impact cash flow and would seriously harm our
business,  financial  condition  and  results  of  operations.

WE WILL NEED TO INTRODUCE NEW PRODUCTS AND PRODUCT ENHANCEMENTS TO INCREASE
REVENUE.

     The  successful  operation  of  our  business  depends  on  our  ability to
anticipate  market  needs  and to develop and introduce new products and product
enhancements  that  respond  to  technological  changes  or  evolving  industry
standards  on  a  timely and cost-effective basis. Our products are complex, and
new products may take longer to develop and require more capital to develop than
originally  anticipated.  In  addition,  products  that  we  may develop may not
achieve  commercial acceptance. Consequently the products we develop may be made
obsolete  by  competitive  products  before  we generate revenue or profits from
their  sale. Our products may contain defects or have unacceptable manufacturing
yields  when  first introduced or as new versions are released. We must continue
to  develop  leading-edge  products  and introduce them to the commercial market
quickly  in  order  to  be  successful.  This  development activity is a lengthy
process and requires significant resources. Many of our competitors have greater
resources  and  technical  staffs  than  we  do.  Our  failure  to  produce
technologically  competitive products in a cost-effective manner and on a timely
basis  will  seriously  harm  our  business,  financial condition and results of
operations.


                                       10

OUR MARKETS ARE NEW AND ARE CHARACTERIZED BY RAPID TECHNOLOGICAL CHANGES AND
EVOLVING STANDARDS.

     The  markets  we  serve  are  characterized by rapid technological changes,
frequent  new  product  introductions,  changes  in  customer  requirements  and
evolving  industry standards. In developing our products, we have made, and will
continue  to  make,  assumptions with respect to which standards will be adopted
within  our  industry.  If the standards that are actually adopted are different
from  those  that  we  have  chosen  to  support,  our  products may not achieve
significant  market  acceptance.

     There  are  several  existing  standards  in  the  communications  industry
including the Telcordia GR1209 and GR1221 standards. Several of our existing and
potential  customers require or will require compliance with these standards. We
continue  to make progress in achieving compliance with these standards and have
produced  DWDM  components  that achieve compliance with some but not all of the
requirements  of  these standards. During the quarter ended December 31, 2001 we
made significant improvements in the environmental performance of our DWDMs, but
are currently not able meet all Telcordia requirements and have not begun formal
testing  under  Telcordia  specifications.  If  we  are  unable  to achieve full
compliance with these and other standards, our business, financial condition and
results  of  operations  will  be  adversely  affected.

DEMAND FOR OUR PRODUCTS IS SUBJECT TO SIGNIFICANT FLUCTUATION.

     Demand  for  our products is dependent on several factors including capital
expenditures  in  the  communications  industry.  Capital  expenditures  can  be
cyclical  in  nature  and  result  in  protracted  periods of reduced demand for
component  parts. Similarly, periods of slow economic expansion or recession can
result in periods of reduced demand for our products. The continuing slowdown of
the  US economy and uncertainty related to the timing and extent of recovery has
contributed  to  the decline in demand for components used in the communications
industry.  Periods of reduced demand will harm our business, financial condition
and  results  of  operations.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK.

     Our exposure to market risk for changes in interest rates relates primarily
to  our  investment portfolio. We invest in short-term securities of high credit
issuers  with  maturities  ranging  from  overnight up to 24 months. The average
maturity of the portfolio does not exceed 12 months. The portfolio includes only
marketable  securities  with  active  secondary  or  resale  markets  to  ensure
liquidity. We have no investments denominated in foreign country currencies and,
therefore,  our  investments  are  not  subject  to  foreign  exchange  risk.
