Laser and LED reliability update

The reliability of various types of InGaAsP/InP lasers and LEDs is reviewed with regard to failure modes and systems requirements. A systematic exposition, including the degradation modes that govern lifetime, is given. Optical transmission systems are reviewed in general terms. Surface-emitting LEDs and lasers are mainly discussed; edge-emitting LEDs are considered briefly. Degradation modes of optical devices and spectral aspects of reliability for distributed-feedback (DFB) lasers are described.<
