Abstract :
A high-speed photodetector has been demonstrated. Prototype silicon devices have detection bandwidths of 5 GHz and are limited by neither the saturation-velocity transit time nor the carrier lifetime. These detectors use a combination of the Dember effect and the east of generating fine photocarrier gratings, and scale to bandwidths of several hundred gigahertz.<>
