Abstract

Special processing of rapid thermal annealing on the cavity coating films for 1950 nm wavelength antimonide quantum well Laser diodes are studied. The maximum output power of the laser is greatly improved by RTA process on cavity facet films from around 610mW to above 700mW. The power conversion efficiency is further improved by the simple process by 23.2% than that of the laser coated. And the laser devices become more reliable and have extended service life after the process.
