Optically activated charge domain model for high-gain GaAs photoconductive switches

A model for theoretical analysis of nonlinear (or high gain) mode of photoconductive semiconductor switches (PCSS's) has been proposed. The switching transition of high-gain PCSS's can be described with an optically activated luminous charge domain. The formation and radiation transit, accumulation of the charge domain are related with the triggering and sustaining phrases of PCSS's, respectively.
