摘要：

We introduce a semiconductor distributed feedback (DFB) in which the grating is fabricated out of quantum well (QW) or superlattice multilayers. This approach provides a very simple and effective scheme for achieving gain (loss)-coupled DFB lasers. The present idea was successfully demonstrated with a 1.55-mu-m wavelength 6-QW In0.6Ga0.4As (5 nm)/InGaAsP (band-gap wavelength = 1.25-mu-m, 18.6 nm) separate confinement heterostructure DFB laser utilizing only a 2-QW In0.62Ga0.38As (4 nm)/InP (9.3 nm) as the grating.
