Title: Monolithic, High-Speed Fiber-Optic Switching Array for Lidar
Agency: NASA
Contract: NNG06CA01C
Award Amount: $599,600.00


This NASA SBIR Phase II effort will develop a 1 x 10 prototype non-mechanical fiber optic switch for use with high power lasers. The proposed optical device is a fiber-based multi-channel switch to rapidly switch a fiber-coupled laser among ten output channels as an integral part of a fiber-based fixed-array laser transmitter for next-generation NASA lidar systems. The key innovation is the use of an arrangement of electro-optic prisms in a nonlinear optical crystal created through domain reversal to direct the laser into one of many possible output fibers. This design will provide several important features that are required yet not currently available in a fiber switch in order to achieve a fiber-arrayed lidar source. These features include high optical power handling, reduced crosstalk, low optical loss, fast switching times, low power consumption, and robust construction in a monolithic package with no moving parts. A packaged device will undergo preliminary flight qualification testing and reliability analysis. The Phase II effort will deliver a compact, packaged 1x10 electro-optic fiber switch that meets specifications and is ready for testing in a NASA all-fiber lidar system.
