   APA OPTICS, INC. REPORTS LOSS FOR SECOND QUARTER AND FIRST 6 MONTHS OF FISCAL
                                      2003

              Cash Position Remains Strong with $29 million On Hand

Minneapolis,  MN,  October  29,  2002  -- APA Optics, Inc. (Nasdaq: APAT), today
reported  a  net loss of $1,318,737, or 11 cents a share, for the second quarter
of fiscal 2003, ended September 30, 2002, as compared to the loss of $1,364,499,
or 11 cents a share, posted for the second quarter of its 2002 fiscal year.  The
decreased  loss  was  attributable  to  reduced  operating  expenses.

"Our  financial  results  reflect  the  stalled economy in general, and in fiber
optics  communications  in  particular",  commented Anil Jain, the president and
chief  executive  officer.  "We  continue  to  monitor the fiber optic component
marketplace  but  do not see a rebound in the near future, particularly for long
haul  applications.  We also believe that the market for optical components will
be  highly competitive and will result in significantly lower prices, due to the
entry of a large number of Asian manufacturers. We recently took steps to reduce
our  workforce,  mainly  in  fiber  optic  component  manufacturing,  and  lower
operating  expenses  in  an  effort  to  preserve  cash," said Jain. The Company
expects  to  see  the benefits of the latest cost cutting measures in the fiscal
third  quarter ending December 31, 2002. "We are modifying our business plans to
focus  on  developing  and  delivering  packaged  solutions  for  fiber  optic
communication  applications.  Most  of the components in these solutions will be
supplied  by  Asian  manufacturers,"  added  Jain.

APA  continues  to  pursue  opportunities  in  Gallium  Nitride  (GaN)  based UV
detection  products  and  its  R&D  activities  in  the  area  of  GaN  based
Hetero-junction Field Effect Transistors (HFETs) for high-speed communication, a
technology  with  substantial  market  potential.  "We  believe  our  GaN  based
technology  and  our  patents will be an instrumental part of APA Optics, Inc.'s
future  success,"  said  Jain.

For the first six months of fiscal year 2003, the Company experienced a net loss
of  $2,571,730,  or 22 cents a share, as compared to a loss of $2,009,560, or 17
cents  a  share,  reported  for  the  first  six months of fiscal 2002. Revenues
decreased  for  the first six months, with $111,351 reported for fiscal 2003, as
compared  to  $521,909  for  the  first  six  months  of  fiscal  2002.

     The  weighted average shares outstanding for the second quarter of the 2003
     fiscal  year  totaled,  11,874,957  as  compared to the 11,917,465 weighted
     average  shares  outstanding  during  the  three months ended September 30,
     2001.  For  the  six  months  ended September 30, 2002 the weighted average
     shares  outstanding  were  11,875,396  compared  to  11,917,378 for the six
     months  ended  September  30,  2001.

On October 1, 2002, the Company extended its stock repurchase plan. "We continue
to  believe  our  stock  is  undervalued  and plan to repurchase shares to cover
current  and  future  option  and  warrant  commitments,"  said  Jain. Under the
extension,  the  Company  may purchase up to the greater of 500,000 shares or $2
million  dollars  of its common stock. As of September 30, 2002, the Company had
repurchased  46,750  shares  for  a  total  of  approximately  $99,000.
