Dynamic characteristics of partly gain-coupled multiple-quantum-well InGaAsP distributed feedback laser diodes have been investigated. Basic dynamic parameters (differential gain, K-factor, differential carrier lifetime) were found out. It is shown that the increase of coupling coefficient results not only in both oscillation and damping frequency increasing, but also in time-resolved frequency chirp oscillation decreasing. Relation between K-factor and differential carrier lifetime and their correlation with differential gain indicates essential differential gain role in dynamic parameter variance. A possibility to simulate the modulation characteristics of partly gain-coupled distributed feedback laser diodes using simple rate equations for carrier and photon density has been shown. Chirp and optical power pulses obtained by time-resolved frequency chirp measurements were compared with modelled ones.
