Abstract
This Phase II SBIR describes the fabrication and characterization of a position sensitive detector with internal gain. Phase I research demonstrated the fabrication of several position sensitive avalanche photodiodes (APDs), including quadrant and lateral-effect photodiodes. With position resolution equivalent to commercially available silicon detectors, but responsivity three orders of magnitude times greater, these detectors offer superior performance over existing position sensitive devices. Using RMD?s advanced planar processing technology, the position sensitive detectors will be further optimized with emphasis on applications for free-space optical communication systems operating at near-infrared (near-IR) wavelengths. The ultimate goal of this program is to develop a manufacturable high speed, low noise position-sensitive APD module. The APD and electronics for readout and data logging will be included in the final module, a valuable tool for long distance communication and LADAR operation.
