Abstract
A high differential gain of 9.3 x 10(-16) cm(2) is obtained in GaInAs- AlGaInAs 1.55-mu m multiquantum-well lasers with 1% compressive strain grown by molecular-beam epitaxy, This is the highest ever achieved in this material system. The model-solid theory and an approximate k . p method are incorporated in the theoretical gain calculation that prov ides a detailed understanding of the experimental results and guidance to further improvement.
