ABSTRACT:
Sum frequency generating devices are disclosed. The devices include a waveguide having a multilayer structure comprising at least one nonlinear semiconductor material. In a preferred embodiment, each of the layers of the multilayer structure has the same thickness and alternate layers have a first and a second predetermined refractive index. The sum frequency output generated by two contra-propagating beams of fundamental wavelengths within the waveguide is enhanced by the multilayer structure of the waveguide. The sum frequency output is in a direction different from that of the waveguide and contrapropagating fundamental beams.
