Abstract
An array of photon counting phototoreceivers is constructed as an imager with micro-digitized pixels. Each photoreciever comprises a vertical cavity optical amplifier (VCSOA) as an optical amplifier, an avalanche photodiode as detector and an analog-to-digital converter (ADC) in an integrated structure. The ADC serves as a 1-bit digitizer and uses a resonant tunneling bipolar transistor RTBT. While the preferred embodiment of the invention have been described, it will be apparent to those skilled in the art that various modifications may be made to the embodiments without departing from the spirit of the present invention. Such modifications are all within the scope of the present invention.
