AXT, Inc. announces 980 NM laser diode products, ion-implant VCSEL devices

The VCSEL/LD Technologies Division of AXT, Inc. (Nasdaq: AXTI), a supplier of customized VCSEL and edge-emitter lasers for telecommunications and data communications applications, announces volume production of 980nm FP Edge-Emitter lasers.

The 980nm lasers exhibit stable single-mode operation with output power up to 200mW and threshold currents less than 10mA and slope efficiency better than 0.9W/A. Initial reliability tests have shown favorable results and long-term tests are currently underway. The lasers are offered with both aluminum and aluminum-free structures, and are available as unpackaged chips or in standard TO-can packages.

AXT also announced volume production of ion-implant VCSEL devices designed for fiber optic applications such as CWDM (coarse wavelength division multiplexing) data communications.

The devices are available with custom-matched wavelength spacing from 780nm to 870nm, and can be tailored to meet a variety of customer specific product designs. The devices have stable power output of up to 13mW and can be modulated at frequencies in excess of 2.1 GHz. Device reliability has been extensively tested and has been demonstrated to exceed current industry benchmarks.
