Abstract
This project will focus on fabricating and optimizing a photodetector that utilizes the emerging technology of internal discrete amplification to create photon-counting sensitivity detectors with very high gain, ultra low noise, high quantum efficiency and GHz bandwidth for optical communications in the spectral range of 1.06 ?m to 1.6 ?m. Extensive modeling during Phase I of this project has permitted to optimize the design and develop manufacturing steps to produce such a photodetector. The detectors will have performance parameters significantly superior to those of conventional avalanche photodiodes and photomultiplier tubes to and should meet and exceed NASA stated mission goals of boosting data transfer rates by a factor of 10-100 relative to the current state of the art. The expected performance parameters include a GHz bandwidth (with a 10 GHz long term goal), gain of 10,000 to 100,000, excess noise factor less than 1.07, saturation levels greater than 50Mcounts/s (higher expected), and flexibility in the choice of active area size and shape, including the ability to create detector arrays. These new capabilities could lead to important advances in deep space and other optical communication applications.
