Abstract: Fiber optic amplification includes a photonic crystal fiber coupled to a pump laser through a first coupler. The pump laser emits a first electromagnetic radiation wave into the photonic crystal fiber at a first oscillation frequency and a second electromagnetic radiation wave into the photonic crystal fiber at a second oscillation frequency equaling the first oscillation frequency. The first and second electromagnetic radiation waves interact to generate a signal comprising an electromagnetic radiation wave at a third oscillation frequency and an idler comprising a fourth electromagnetic radiation wave at a fourth oscillation frequency to be generated and amplified through parametric amplification. Parametric amplification is achieved by four wave mixing. The photonic crystal fiber emits a parametric output signal based on the four wave mixing. A nonlinear crystal frequency doubles the parametric output signal through second-harmonic generation.

Abstract: A non-mechanical optical beam steering device includes one or more polarization gratings (PG) coupled to one or more Steerable Electro-Evanescent Optical Refractors (SEEOR). It provides the coarse steering advantage of the PG and also the continuous fine steering advantage of the SEEOR. The result is far less complexity, size, weight, and cost over the alternative non-mechanical beam steering approaches as well as considerably less complexity, size, weight, cost, scanning-time, and mechanical breakdown over the more traditional gimbaled mirrors commonly used.
