Monte Carlo simulation of response time of photoconductive semiconductor switches

Monte Carlo simulation method has been used to study the linear mode of photoconductive semiconductor switches (PCSS). Its triggered source is a femtosecond laser pulse. The simulation results are well in agreement with experiment data, so the model is accurate. Based on the model, some important factors which influence the response time of PCSS have been analyzed by computer simulation. Then the sizes of these parameters that make an important contribution to get better response time have been deduced. From this simulation analysis, it is sure that some experiment conditions can be used more enough. In other words, the response time can be further shortened under the same experiment condition. Moreover, the transition from linear mode to non-linear mode has been analyzed using this model.
