Optical parametric device

摘要: An optical parametric device is described which may be used as an amplifier, oscillator, or frequency converter, and operable in the infrared visible spectral regions. The utilizes a dielectric waveguide tuned cavity, structure comprise depletion layer of semiconductor junction, material exhibits nonlinear susceptibility. intense, appropriately oriented, pump induces non-linear electric polarization structure. Traveling wave discrete circuit interaction occurs within between input signal. Under appropriate conditions, oscillation, amplification, and/or conversion obtained.
