Abstract
We studied ultrafast transport dynamics of ultrawide-band surface-normal p-i-n photodetectors under high illumination and high field using electro-optic sampling techniques. Under reverse bias and high illumination, saturation nonlinearities are dominated by the collapse of the electric field from space charge screening. A transient forward external current is observed with a duration less than 4 ps. The external bias required to compensate these saturation effects increases with increased illumination.
