Influence of device fabrication parameters on gradual degradation of (AlGa)As cw laser diodes

Abstract

Several factors not previously associated with cw laser degradation are shown to influence the life and reliability of (AlGa)As cw injection laser diodes. They include zinc diffusion, sawing damage, and facet erosion. When proper attention is paid to these factors, lasers showing no significant degradation for at least 2000 h can be made.
