Eospace Inc. SBIR Phase I Award, September 2021

Develop and package a 2 x 2 single mode optical switch operating at 1.55 µm wavelength capable of switching speeds below 1 µs with a directivity of 50 dB and an excess loss of less than 1.0 dB with a continuous intensity change from port-to-port for routing RF/analog signals via singlemode fibers to different locations within the NAVY airframe. The optical switches must be low SWaP and capable of meeting the extended temperature range requirements (-40 °C to 100 °C).
