Abstract
A high index contrast waveguide based source for radiation. In some embodiments, the radiation is in the 0.5-14 Terahertz regime. Waveguides are provided that permit the generation of radiation at the sum and/or difference frequency of two input beams. In order to control the power level within the waveguide, embodiments in which pluralities of similar or identical waveguide are provided, and the input radiation is divided among the plurality of waveguides. The output radiation can be steered by applying phased array methods and principles.
