AXT debuts 1550nm FP source lasers (Fiber News)
AXT (Fremont, CA) has introduced a range of 1550 nm edge-emitting Fabry Perot (FP) lasers operating at 2.5 Gbit/s for SONET transceivers used in metro and long-haul applications. Exhibiting a high-temperature power output of 10 mW at 85C and peak linear power of 20 mW, these devices offer threshold currents of 10 mA and slope efficiencies of up to 0.5 mW/mA. The new laser is currently being sampled, with volume quantities expected later in the third quarter. "We are very pleased with the performance of our new 1550 nm lasers," commented Morris Young, president and CEO. "In a very short period of time, we have developed a world-class product that has numerous uses in rapidly growing markets such as metro area networks. Our power output exceeds that of most other 1550 nm lasers currently available, and the efficiency is approximately 50% better than most. This will help our customers achieve more aggressive transceiver designs with fewer cooling requirements."
