Monolithic, High-Speed Fiber-Optic Switching Array for Lidar, Phase I

Completed

Description

The proposed optical device is a fiber-based multi-channel switch to quickly switch a fiber-coupled laser among many possible output channels to create 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 created in a nonlinear optical crystal 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, such as 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. The Phase I effort will demonstrate feasibility of the approach by creating a preliminary device with representative features to assess the suitability of the technology for use in lidar systems.

How to get involved

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
