Abstract

A dielectric waveguide is disposed adjacent to a diode array which allows for coupling of energy therebetween. The waveguide has a core section and a cladding section encompassing a core section except in a portion thereof. The diode array is disposed adjacent to the exposed core portion at a proximity which allows evanescent coupling of energy between energy traversing the waveguide and the diodes of the diode array. A variety of microwave devices may be provided by this arrangement which include a signal source, detector, harmonic generator, upconverter, down-converter, or power combiner, depending upon the types of signals and manner of application of the signals applied to the waveguide and to the diode array.
