摘要：

A partly gain-coupled 1.55-mum distributed feedback (DFB) laser with a gain coupling in a strained-layer multiple-quantum-well (MQW) active region is reported with high relaxation oscillation frequency and maximum intrinsic bandwidth of 28 GHz. A high effective differential gain of 1.80 x 10(-15) cm2 was achieved, which may be interpreted as the result of the strain effect in MQW active region as well as a combination of the longitudinal gain / index coupling mechanism and fast lateral carrier injection from the cladding layers into the wells.
