Paper Abstract

A gain-guide tapered stripe laser was fabricated by metalorganic chemical vapor deposition. Improved characteristics, such asoa low threshold current of 48mA, a maximum temperature for continuous wave operation of 81C and an small astigmatic difference of 25pm, have been achieved. Sixteen cdevices have been operating without significant degradation for more than 5000 hours at 50C with a constant output power of 3mW. A high output power of 250mW has also obtained by the broad stripe laser.
