High-speed zero-bias waveguide photodetectors
Abstract
An InGaAsP waveguide PIN photodetector is described that (unlike conventional PINs) provides for light absorption perpendicular to current collection, a feature that results in high-speed, high-efficiency, and relatively bias-insensitive operation. The uncoated, packaged device has displayed impulse response of 40 ps and efficiency of 25 percent at zero bias.
