Abstract

For the problem of low modulation rate and narrow modulation bandwidth of semiconductor lasers(LD),according to the LD rate equation, the expression of the relaxation oscillation frequency is derived.The influence of internal parameters on the modulation characteristics of laser is simulated from two aspects: time domain and frequency domain. The simulation results verify the correctness of the theoretical derivation. In addition, measures for improving the modulation characteristics of lasers are proposed. The results show that the larger modulation bandwidth and higher modulation rate can be achieved by increasing the steady state photon density and differential gain coefficient and reducing the photon lifetime and the gain saturation factor.
