摘要： Metal oxide films such as lithium niobate are formed in an amorphous state on a substrate such as lithium niobate and can be readily etched by conventional liquid or dry etchants. The amorphous film may then be converted by annealing to a crystalline form well suited to formation of electro-optical devices.

摘要： A two-dimensional second order nonlinear lattice formed in a lattice body is utilized for performing a one-step optical carrier wavelength interchange between pairs of input optical signals. The lattice body includes sensitized regions arranged in a two-dimensional array in a matrix material with the sensitized regions differing from the matrix material in the sign of the second order susceptibility. When an optical pump signal is coupled to the lattice body at a frequency corresponding to the sum of the frequencies of the two input signals, nonlinear interactions in the lattice body produce wavelength interchange between the input signals, resulting in angularly deflected optical signals exiting the lattice body in which the signal information on the input signals is interchanged between the carrier frequencies of the two input signals. The apparatus can be utilized to provide switching of optical signals and wavelength interchange for applications such as in wavelength division multiplexed communication systems.

摘要： A THz radiation source comprising a dual waveguide heterostructure is provided. The dual waveguide heterostructure includes an optical waveguide contained within a larger THz waveguide layered structure. The radiation source provides a coherent guided wave of THz radiation which is generated via difference frequency mixing in a gain medium with a large second-order nonlinearity and propagated with low THz loss by a dielectric medium in the layered waveguide structure. The THz radiation source is compact, has a high power output, and may be operated in continuous-wave (CW) mode at room temperature.
