摘要：
InGaAs/GaAs strained quantum well gain guided lasers failed during aging tests. A front facet damage with formation of a dark defect close to the mirror has been evidenced with infrared and scanning optical microscopy. The defects are responsible for large losses into the cavity, which cause an higher density of injected carriers to sustain lasing and a blue shift of about 40 nm in the optical spectrum.
