Abstract :
Frequency responses of 1.3- mu m InGaAsP/InP semiconductor lasers emitting in both transverse-electric and transverse-magnetic polarizations have been measured. It is found that lasers with different polarization-dependent power-versus-current characteristics show different polarization-dependent frequency responses. A polarization-dependent rate-equation model has been used with small-signal analysis to simulate the observations. The relative modulation bandwidths and the low-frequency modulation of the two polarizations can be explained. This model does not fit well at high frequencies because of the parasitics.<>
