Abstract

A theoretical and experimental study of a graded-index separate confinement heterostructure (GRIN-SCH) distributed feedback (DFB) multiquantum-well (MQW) diode laser emitting at 1.55 μm subject to external light injection from several lasers is presented. Lang´s model for the classical single master-slave configuration is extended to include light injection from several master lasers. Free carrier transport effects are taken into account. An experimental validation of the model for two master lasers is made by means of a quantitative comparison between measured and calculated optical spectra. A fiber optics experimental setup makes it possible to measure precisely the power which is injected into the slave laser from each master laser. Measurements and model are in good quantitative agreement
