A new kind of high-speed photodetector has been constructed utilizing the anisotropic etching technique. It is demonstrated that, functioning as an edge-incident photodiode, the detector responds reliably to subnanosecond light pulses with 40% overall quantum efficiency. And, functioning as a phototransistor, it responds to cw radiation with a current gain. Compatibility with existing planar processing is another feature. Possible mechanisms involved are discussed.
