Title: System for improving signal-to-noise ratio of a communication signal

Abstract

A superconductive resonant cavity is energized with radio frequency energy. The cavity includes a tuning stub having a piece of semiconductor material mounted on the end. An incoming communication signal modulates a light source which is optically coupled to the semiconductor by a fiber optic bundle. piece of semiconductor material mounted on the end. An incoming communication signal modulates a light source which is optically coupled to the semiconductor by a fiber optic bundle. This varies the dielectric constant of the semiconductor which, in turn, varies the resonant frequency of the cavity. An angle modulation demodulator senses the frequency of the radio frequency oscillations in the cavity and produces a replica of the communication signal with improved signal to noise ratio.
