Integrated Planar Lightwave Circuits for UV Generation and Phase Modulation

The primary goal of this SBIR effort is delivery of a compact, robust, highly efficient, fiber-coupled UV module to provide the required 355nm light for integration into HSRL's UV interferometric-based measurement system. An additional goal of this effort is to prototype a compact, robust, fiber-coupled UV PLC module which produces the required spectrally formatted 355nm light for stabilization of the HSRL's UV interferometric filter, a component required for the accurate measurement of critical aerosol microphysical properties. This approach is enabled by AdvR's patented submount poling technique together with AdvR's integrated Planar Lightwave Circuit (PLC) technology. The UV 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 future space-based platforms.
