    Abstract: Apparatus and method for high-power multi-function millimeter-wavelength (THz-frequency) signal generation using OPO and DFG in a single cavity. In some embodiments, the OPO-DFG cavity includes an optical parametric oscillator (OPO) non-linear material that receives pump light I P having pump-light frequency and generates two different lower intermediate frequencies of light - an OPO-signal beam I S and a spatially/temporally overlapping OPO-idler beam I I . A difference-frequency generator non-linear material then receives the two intermediate-frequency beams II and IS, and the DFG then generates a THz-frequency output signal that has a frequency equal to the difference between the two intermediate frequencies. In some embodiments, a single-piece crystal of non-linear material is used for both OPO and DFG functions. Some embodiments use a bow-tie ring having four mirrors that define the optical path: an IP-beam-entry mirror, an IP-light-extraction mirror to remove unconverted I P -beam, an II-beam-extraction mirror, and an IS-beam-extraction mirror, and a fifth I THz -beam-extraction mirror.

    Abstract: A microphotonic device (2, 24) is provided. The microphotonic device includes a membrane structure (6) that can experience strain. A waveguide element is formed on the membrane structure so that when the membrane structure is strained, the geometrical structure of the waveguide element is turned to a selective amount. Preferably, the membrane comprises a sub-micron SiO2 layer and is deformed through piezoelectric P2T actuator (4). Examples of waveguide elements are microring resonator (8), microracetrack resonator (30, 34), 1D and 2D photonic crystals.
