High Power, Robust, Polarization Insensitive Integrated Optic Phase Modulators and Polarization Controllers

In Phase I, SRICO will experimentally demonstrate the concept and complete the design of a compact robust, polarization insensitive integrated optic phase modulator and polarization controller module for Phase II development. SRICO proposes to develop a phase modulator and polarization controller based on new waveguide technologies to handle high optical power and novel device geometries to achieve wide bandwidth and low drive voltage. Performance, size and cost benefits may be achieved by combining phase modulation and polarization control in a single module suitable for use in high power fiber laser beam combiners. SRICOs integrated optic concept for a monolithically integrated optical polarization controller and phase modulator in a single robust package will enable a wide-band, high power spectral and coherent beam combining solution with improved optical efficiency and reduced size, weight, power, and cost (SWAP-C).
