Abstract

Using small-signal analysis based on rate equations, the effect of carrier transport on the modulation bandwidth of multiple quantum well lasers (MQW) is analyzed. Based on effective transport time model, it is shown that there is an optimum value of the ratio between carrier capture time and escape time, at which the modulation bandwidth of MQW lasers achieves maximum. The theoretical results were compared with experimental data and satisfactory agreement has been found. Drift-diffusion approach has also been introduced, and some preliminary results are presented.
