Abstract :
In conclusion, the time to catastrophic optical damage (COD) failures of 980-nm pump InGaAs strained double quantum well lasers was estimated by using accelerated aging tests of over 200 mW. The laser passivated with the SiNx-Al2O3 combined films has a lifetime of over 130,000 h at a 90-mW fiber-coupled power level, which is suitable for applications to practical EDFA systems
