ITEM  2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
OF  OPERATIONS


     Statements in this Report about future sales prospects and other matters to
occur  in  the  future  are  forward  looking  statements  and  are  subject  to
uncertainties  due  to many factors, many of which are beyond our control. These
factors  include,  but  are  not  limited  to,  the continued development of our
products,  acceptance  of  those products by potential customers, our ability to
sell  such  products  at  a  profitable  price,  and  our  ability  to  fund our
operations.  For  further  discussion regarding these factors, 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-based  ultraviolet  (UV)  detectors  (both
components  and  integrated  detector/electronic/display  packages)  because  we
believe  that  these  two  product  areas have significant potential markets and
because  we  have  expertise  and/or  patent  positions  related  to  them.

     Most  companies in the communications equipment industry have been affected
by  the  slowdown in telecommunications equipment spending. We recently received
notice  from  a  customer  that  it  was discontinuing development of an optical
system  utilizing  our  DWDM components. As a result, the customer cancelled the
majority  of  an  outstanding  purchase  order for 21 of our DWDM components.

     Weakness  in  the  general  economy,  and  the telecommunications sector in
particular, continues to put downward pressure on component pricing, margins and
profits.  There are an increasing number of manufacturers of DWDMs pursuing this
soft  market  bringing  additional  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.

     During  the  quarter  ended  September  30,  2001,  we  made  significant
improvements  in  the  environmental  performance  of  our  DWDMs. Environmental
performance  is  a  key  test  factor  for  qualification  of our products under
industry  standards  as  promulgated  by  Telcordia.  While  we made significant
progress  in  these  areas,  performance  issues  related  to  environmental
specifications  prevented  us  from  shipping  more  product  during  the second
quarter.  Also, production uniformity issues have resulted in limited production
of  our SunUVWatch(R). These problems were still being resolved as of the end of
October  2001.


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

REVENUES

     Revenues for the quarter ended September 30, 2001, were $87,574, reflecting
a 29% decrease from the comparable period in the preceding fiscal year, and were
$521,909  for  the six months ended September 30, 2001, an increase of 198% over
the  revenues  for  the  comparable  period  in the preceding fiscal year. Lower
demand  for  DWDM  components  and  problems incurred in production resulting in
delayed  shipments  of  components  were the primary factors contributing to the
decline  in  revenues  during  the  most  recent fiscal quarter. The increase in
revenues  for the six months ended September 30, 2001, was largely the result of
sales  of  our  DWDM  components  during  the  first  quarter  of  fiscal  2002.


                                        6

COST  OF  SALES

     Cost  of  sales  increased  $347,596  to  $957,316  for  the  quarter ended
September  30, 2001, reflecting a 57% increase over the comparable period in the
preceding  fiscal  year.  For  the  six months ended September 30, 2001, cost of
sales  increased  $884,376  or  87%  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  penetration 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  decreased  by $57,004 for the quarter
ended  September  30,  2001. This represents a decrease of 19% from research and
development  expenses in the comparable period of the preceding fiscal year. For
the  six  months  ended  September  30,  2001, research and development expenses
decreased  $154,769  or  27%  from the comparable period in the preceding fiscal
year. These decreases are partially the result of classifying a portion of these
expenses as cost of goods sold rather than research and development expenses, as
we  focused more on the production of products for sale and less on research and
development  activities.  We  expect research and development expenses to remain
constant  or  increase  slightly  for  the  foreseeable  future  with  a gradual
expansion  of  our  research  and  product  development  activities.

SELLING,  GENERAL  AND  ADMINISTRATIVE

     Selling,  general  and  administrative  expenses  increased $96,125 for the
quarter  ended September 30, 2001, reflecting a 23% increase over the comparable
period  in  the  preceding  fiscal  year. For the six months ended September 30,
2001,  selling,  general  and  administrative expenses increased $164,854 or 21%
over  the  comparable  period  in  the  preceding  fiscal year. The increase was
primarily  due  to  an increase in personnel and other expenses as we prepare to
market  our  products  and  develop  expanded  internal reporting and management
systems.

LOSS  FROM  OPERATIONS

     The loss from operations expanded to $1,616,258, an increase of $422,605 or
35%  for  the  quarter  ended  September  30, 2001 over the comparable period in
fiscal  2001.  For  the  six  months  ended  September  30,  2001, the loss from
operations increased $547,531 or 25% over the comparable period in the preceding
fiscal  year.  The  increased  loss in the quarter ended September 30, 2001, was
primarily  the  result  of  the  decline  in  revenues  from the previous fiscal
quarter.  Soft  demand  for  DWDM components and problems we incurred related to
production  of  DWDM components were major factors contributing to this decline.

OTHER  INCOME  AND  EXPENSE

     Other  income decreased $344,758 or 58% for the quarter ended September 30,
2001,  from  the  comparable  period  in  fiscal  2001. For the six months ended
September  30,  2001,  other  income increased $45,532 or 7% over the comparable
period in the preceding fiscal year. The decrease for the quarter was 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.  The  increase in other income for the six
months ended September 30, 2001, was primarily the result of the timing of sales
of common stock in the preceding fiscal year and investment of the proceeds that
began  generating  interest  income  during  the  second quarter of fiscal 2001.
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  expansion.


                                        7

NET  LOSS

     The  net  loss for the quarter ended September 30, 2001, was $1,364,499 (or
$0.11 per basic and diluted share), an increase of $767,500 or 129% from the net
loss  reported  for  the  same  period  in fiscal 2001. For the six months ended
September  30, 2001, the net loss was $2,009,560 (or $0.17 per basic and diluted
share),  a  33%  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 six months ended
September  30,  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 September 30,
2001  is  $33,884,252 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 $1,789,378 for the six months ended
September  30,  2001,  compared  to  $1,197,178 for the comparable period in the
preceding fiscal year. The increase reflects increased sales with negative gross
margins  and  increased  costs  associated  with our larger staff and production
facilities.

     We  used  net  cash  of  $931,123 in investing activities in the six months
ended  September  30,  2001,  compared  to  $165,243  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  six months ended
September 30, 2001 totaled $15,379,261. 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 $311,533 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. Additional information regarding
the  stock  repurchase  is  available  in  the  Notes to the Condensed Financial
Statements under Part I and under Part II, Item 6 of this Form 10-Q. For the six
months  ended  September  30,  2000,  net  cash provided by financing activities
totaled  $34,701,388.  We raised $39,810,534 from the sale of common stock, used
$5,033,054 to retire preferred stock and used a net of $76,092 for the scheduled
reduction  of  debt.

     We anticipate a total of approximately $2.5 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. The expenditures will be made in phases to
meet  demand  for  our  products  and  to  allow  us  to respond to new business
opportunities.

     We  believe  we  have  sufficient funds for operations for the remainder of
fiscal  2002  and  beyond.

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 September 30, 2001, we
had  an accumulated deficit of $15.5 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.  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
higher  revenues  while  containing  costs  and  operating expenses if we are to
achieve  profitability.


                                        8

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

     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. We have limited experience in rapidly
increasing  our  manufacturing  capacity  or  in  manufacturing products at high
volumes.  We will be required to hire, train and manage additional manufacturing
personnel  and  improve  our  production  processes  in  order  to  increase our
production capacity. There are numerous risks associated with rapidly increasing
capacity,  including:

     (i)     Difficulties in achieving adequate yields from new manufacturing
             lines,
     (ii)    Difficulty maintaining the precision manufacturing processes
             required by  our  products  while  increasing  capacity,
     (iii)   The inability to timely procure and install the necessary
             equipment, and
     (iv)    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.

     We purchase components that are incorporated into our products from outside
vendors.  If  these vendors fail to supply us with components on a timely basis,
we could experience significant delays in shipping our products. Any significant
interruption 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 system,
both  current  and future. In addition, our products 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, 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  than  originally  anticipated.
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.


                                        9

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 September 30, 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 have
contributed  to  the decline in demand for components used in the communications
industry.  We recently received notice from a customer that it was discontinuing
development of an optical system utilizing our DWDM components. As a result, the
customer  cancelled the  majority of an outstanding purchase order for 21 of our
DWDM  components.  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.
