Optical Communications With A Geiger Mode APD Array
Abstract
In this thesis, I evaluated the theoretical and practical performance of a Geiger mode avalanche photodiode (GM-APD, or Geiger mode APD) array for use in optical communications systems. I designed and implemented a test pattern generator, capable of producing waveforms with OOK and PPM modulations at a variety of symbol rates and duty cycles. Using this pattern generator, I tested the receiver properties over a wide range of data rates and illumination levels, and was able to demonstrate the capability for error-free communications in both modulation formats, up to 78.8Mbps at a sensitivity of 1.8 photons per bit for OOK, and 34.9 Mbps at 2 photons per bit for PPM.
