BROADBAND OPTICAL DETECTORS (1.06-MICRON).
Abstract
Results obtained during the first half of a program to develop a 1.06-micrometer optical detector are discussed. The detector will contain a germanium avalanche photodiode, thermoelectric cooler, biasing circuit, and preamplifier. Work during this half was concentrated on fabrication of both N(+)P and P(+)N photodiodes with a graded guardring to prevent edge breakdown. Diffusion masking problems prevented successful fabrication of the P(+)N structure; however, good N(+)P diodes were fabricated. Diodes with avalanche gains greater than 100 were obtained. Yields were greater than 25%. The design of the photodiode-cooler subassembly is discussed. This package will allow the diode to be cooled below 0 C to reduce the bulk leakage current. (Author)
