Paper Abstract

Silicon APD's (Avalanche Photodiodes) with very low excess noise factors have been developed at RCA. At 830 nm and an average gain of 150, an excess noise factor of 2.6 should be possible in a 100 μm active diameter detector, with a quantum efficiency of 90% and a capacitance of 0.25 pF. When combined with a low-noise preamplifier, it is predicted that direct-detection optical receivers can be constructed with a sensitivity which is within 3 to 4 dB of that achievable with an "ideal" optical receiver.
