The Department of Defense (DOD) is seeking proposals for a Small Business Innovation Research (SBIR) program focused on the topic of "Flexible Integrated Optical Circuit (IOC) Packaging Options for Improved Size Weight and Power (SWaP) in Interferometric Fiber-Optic Gyroscopes (IFOG)". The objective of this topic is to address multiple aspects in the design and packaging of current state-of-the-art Y-branch phase modulator integrated optical circuits (IOCs) to make them more flexible for integration into reduced form factor sensors. The goal is to reduce SWaP requirements while maintaining or outperforming prior generations of sensors. The Phase I of this program expects that the small business would have already demonstrated IOC design capability to address one or more packaging improvement options. Feasibility documentation must be provided to substantiate the scientific and technical merit of the proposed solution. In Phase II, the small business is expected to design, fabricate, and characterize six prototype IOCs that are fully packaged and suitable for testing and integration. The prototypes should be delivered at the end of Phase II. The potential applications of this technology include military/strategic applications, as well as commercial technologies such as Light Detection and Ranging (LIDAR), satellite optical communications, and telecommunications. The project duration is not specified, but the open date for proposal submission is May 15, 2024, and the close date is June 12, 2024.
