High output power and long-term stable operation have been realized in all-MOCVD grown 1.48 micrometers buried heterostructure lasers. For the purpose of high power operation, a diode with a cavity length of 1800 micrometers was mounted junction down. This diode shows the maximum output power of 310 mW at 25 degree(s)C, cw. A preliminary aging test is being carried on at a temperature of 50 degree(s)C with a constant light output of 100 mW for the diodes with cavity length of 900 micrometers and junction up configuration. Long-term stable operation over 3000 hrs and the estimated MTTF of 2.4 X 105 hrs at 50 degree(s)C, 100 mW have been realized. As another advantage of the all-MOCVD process, the uniformity of the laser characteristics is also demonstrated. Lasers with a cavity length of 900 micrometers in junction-up configuration are assembled from a processed 2-inch wafer.
