FREMONT, Calif. -- The VCSEL Technologies Division ofAXT, Inc. (Nasdaq: AXTI), a leading supplier of standard and customized VCSELproducts for telecom and data communications applications, today announcedvolume production of oxide confined VCSEL (vertical-cavity surface-emittinglaser) arrays in 1x12 and 1x4 configurations. These arrays are used in suchapplications as short-reach optical interconnections and optical transceiverapplications, and can include InfiniBand (SM) designs.

Each device within the 850 nm wavelength array can be modulated at datarates in excess of 2.5 Gbps, permitting optical designs with very high datarate products through the use of parallel data channels. The 1x4 array allowsfor modulation speeds reaching 10 Gbps data rates (OC-192) and the 1x12 arraysupports 30 Gbps rates. Typical power output for each VCSEL is 1.0mW withoutput slope efficiencies of 0.45-0.50 mW/mA. Both array forms are availableimmediately in production volumes, and can be tailored to meet a variety ofcustomer specific product designs.

"Today we are announcing yet another exciting VCSEL product for ourcustomers," said Morris Young, president and CEO. "VCSEL arrays are a keyingredient for high-speed parallel optics designs. We are addressing arapidly expanding market with the introduction of these products, as moremanufacturers of high-speed interconnection solutions make use of VCSEL arraysin their designs."
