Classification description:

Semiconductor lasers; Structure or shape of the active region; Materials used for the active region comprising quantum well or superlattice structures, e.g. single quantum well lasers [SQW-lasers], multiple quantum well lasers [MQW-lasers] or graded index separate confinement heterostructure lasers [GRINSCH-lasers] in AB compounds, e.g. AlGaAs-laser, InP-based laser characterised by the materials of the barrier layers based on In(Al)P
