H01S5/3403 - CPC Classification

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] having a strained layer structure in which the strain performs a special function, e.g. general strain effects, strain versus polarisation
