AXT, Inc. Announces 850 nm Oxide VCSEL Devices for High Data-Rate Applications

Production Quantities Available for Modulation Rates in Excess of 3.125 Gbps



Apr 25, 2001, 01:00 ET from AXT, Inc.

    FREMONT, Calif., April 25 /PRNewswire/ -- The VCSEL Technologies Division
 of AXT, Inc. (Nasdaq: AXTI), a leading supplier of standard and customized
 VCSEL and edge-emitter lasers for telecom and data communications
 applications, today announced volume production of oxide confined VCSEL
 (vertical-cavity surface-emitting laser) devices designed for higher data-rate
 fiber optic transmission.   Applications for this product include VSR
 Ethernet, fibre channel for storage area networks (SANs), optical
 interconnections and other optical transceiver applications.
     The 850 nm devices have been successfully modulated at data-rates in
 excess of 3.125 Gbps with typical power output of 1.0mW and peak power output
 exceeding 5.5mW.  The oxide VCSELs are highly efficient, with output slope
 efficiencies of 0.45-0.50 Watt/Amp obtained.  Devices are available
 immediately in production volumes, and can be tailored to meet a variety of
 customer specific product designs.
     "This is yet another milestone for our VCSEL Technologies division," said
 Morris Young, CEO of AXT. "We have steadily increased the data transmission
 rates for our VCSEL products over the past few months. Because oxide devices
 can operate at higher speeds than a traditional implanted device, we are now
 able to satisfy our customers' demands for higher speed VCSEL products.
     "The market for VCSEL products is in its infancy and is growing rapidly.
 Today, we are seeing VCSELs being used in a greater number of data
 communication applications, as their performance improves. We will continue to
 focus on increasing our data transmission rates, and are committed to
 capturing a significant portion of the VCSEL market," he said.
     The VCSEL transceiver market is expected to reach over $3.4 billion by
 2004, as forecast by ElectroniCast Corp.

     Safe Harbor Statement
     This press release contains forward-looking statements regarding the
 availability, performance and market acceptance of new VCSEL products, the
 company's ability to bring these products to market and the current market
 conditions in the opto-electronic device industry. Forward-looking statements
 address matters that are subject to a number of risks and uncertainties,
 including but not limited to: unpredictable fluctuations in our operating
 results due, among other factors, to the timing, volume, and pricing of orders
 from customers; an inability to expand our manufacturing capacity to meet
 demand for our products; failure to achieve anticipated sales of our new VCSEL
 products; potential slowdowns in the wireless handset and fiber optics markets
 which may cause our customers to reduce or delay orders of our products; if we
 do not comply with environmental and other regulations we may incur large
 fines and delays in manufacturing our products; and if we experience frequent
 electrical power outages our production could be reduced and we may incur
 costs related to interrupted productions runs. Reference is made to AXT's
 filings with the Securities and Exchange Commission, including AXT's Form 10-K
 for the year ended December 31, 2000 and its Form 10-Qs, and to AXT's Form
 S-3, for further discussion of risks and uncertainties regarding AXT's
 business.
