ZnMgSSe-based laser diodes

摘要

Abstract: We summarize here recent progress in II-VI blue-green semiconductor laser diodes (LDs). ZnMgSSe quaternary alloy, a promising material for the cladding layer, has enabled us to realize a long lifetime exceeding 100h with improvements in the active layer, the electrode, and growth techniques. Studies of degradation have revealed that II-VI LDs degrade not catastrophically, but gradually with enhancement by electron-hole recombination at defect sites. !24
