Abstract
A quasi-optical integrated circuit which makes use of a high resistivity k single crystal intrinsic semiconductor as a low loss quasi-optical wave transmission medium for millimeter and submillimeter waves having one or more circuit elements or devices disposed either at or near the surface of a portion of the semiconductor, or formed within a portion of either the semiconductor transmission medium or a portion of a high resistivity single crystal intrinsic semiconductor appendage to said semiconductor transmission medium. By varying the potential applied to said elements or devices, one can control either the phase or the amplitude of quasi-optical wave propagation along the semiconductor waveguide; moreover, solid state devices such as quasi-optical generators, mixers and detectors can be formed within the semiconductor wave transmission medium itself. Quasi-optical generators also can be obtained by inserting a negative resistance device in an aperture disposed within a cavity resonator which is made of a material of high dielectric constant and high resistivity.
