Integrated Planar Lightwave Circuits for UV Generation and Phase Modulation
This SBIR Phase I effort proposes to establish the feasibility of developing a UV Planar Lightwave Circuit (PLC); a compact, highly efficient, waveguide-based frequency conversion module for the generation of phase modulated UV radiation for use in multi-wavelength lidar applications such as NASA LaRC's HSRL program. The proposed module will provide phase modulated 355 nm radiation for calibration and stabilization of HSRL's UV interferometric filter, a component required for the accurate measurement of critical aerosol microphysical properties. The goal of the Phase II effort will be the optimization and integration of a compact, monolithic, fiber coupled UV PLC into the next generation HSLR seed laser system. The PLC concept advances NASA's state-of-the-art lidar systems due to its compact, efficient, and reliable design, thus enabling use on small aircraft and space based platforms.
