The Department of Defense (DOD) is seeking proposals for the development of fast 1-to-N polarization maintaining fiber optical switches for the Near Infrared (NIR). The objective of this solicitation is to develop a technology that allows for near-infrared light in a fiber waveguide to be rapidly and efficiently directed along one of many fiber waveguides in nanosecond scale time periods. The technology will be used in atomic accelerometers for advanced inertial navigation and timing systems. The switch must have rise and fall times on the order of nanoseconds and be capable of MHz repetition rates. It must also have high reliability, low insertion loss, ultra-low crosstalk, and at least four ports. The operating wavelength is 780 nm, and the fiber type is polarization maintaining. The solicitation is open for proposals until June 12, 2024. Phase I of the project will involve a design and materials study, while Phase II will focus on fabricating, testing, and delivering three prototypes. The technology has potential applications in the telecom industry, Light Detection and Ranging (LIDAR) systems, and future quantum network infrastructure.
