Abstract

In this paper, the response of a surface-normal p-i-n photodetector that was incorporated in an optically controlled optical gate was analyzed using short-pulsed, high-energy optical inputs with small spot sizes. Simulation results based in part on diffusive conduction were compared against the experimental data, providing an understanding of the device response. Results also demonstrated that p-i-n photodetectors may be designed so that reducing the spot size, counterintuitively, results in negligible additional field screening.
