Abstract : A quasi-optical integrated circuit which makes use of a high resistivity bulk single crystal intrinsic semiconductor as a low loss quasi-optical wave transmission medium for millimeter and submillimeter waves is described. This has one or more circuit elements or devices disposed either at or near the surface of a portion of the semiconductor. 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.
