Abstract

We report a new tunable phasematching technique for submillimeter and far-infrared difference-frequency generation by optical lasers. We use a multiple waveguide principle based on an optical waveguide embedded in a low-loss modified H-guide. The same phasematching technique also permits the development of a Gigahertz electro-optic modulator design. In order to use uniaxial electro-optic materials, the theory of the H-guide was extended to determine the appropriate crystal orientations and dispersion equations. Numerically generated design curves are presented for tunable electro-optic modulators designed for 3-10 Gigahertz operation. A brief discussion of other possible designs and applications based on the multiple-waveguide method of phasematching is also given.
