The quantum noise suppressed photon coupled transistor

Abstract

We outline the characteristics, potential applications and proposed OEIC fabrication of a quantum noise suppressed photon coupled transistor (QNS PCT), the first practical optoelectronic device to utilize amplitude squeezed ("quiet") light. A PCT comprises light-emitting and light-detecting junctions electrically and optically coupled together. It is similar to a bipolar transistor except that photons rather than minority carriers are transported from collector to emitter. The noise performance is studied. The device is modelled using LEDs and a PIN photodiode.
