摘要：

Frequency modulation characteristics of AlGaAs lasers having three kinds of stripe structures, channeled substrate planar (CSP), buried hetero- (BH) and transverse junction stripe (TJS) structures, are investigated. The phase relation between the frequency modulation and modulation current show two types of dependence on the modulation frequency. It is shown that this result is explained well by considering inhomogeneous carrier density distributions in the lateral direction across active layers.
