"Large-signal response of p-i-n photodetectors using short pulses with
small spot sizes," IEEE J. Quantum Electron. 40, 143-151 (2004)
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.
