A model for a gallium arsenide(GaAs:Si:Cu) photoconductive switch has been developed and solved to determine the performance of the device in bistable switch applications. Simulation studies are performed on a GaAs switch system composed of different density of deep levels to investigate the influence of deep traps in a photoconductive switch system. The computer results show that the initial electron occupation at the deep accepters controls the on-state conductivity of the switch. The required photon flux to turn off the switch is obtained from the computer simulation.
