The Department of Defense, specifically the Army, is seeking proposals for the development of emerging materials for cryogenic optical modulation as part of the Small Business Innovation Research (SBIR) program. The objective is to create electro-optic modulators (EOM) that exhibit high modulation efficiency at low temperatures (below 100 K) to enhance data transmission capabilities in high-performance infrared imaging systems. This initiative is crucial for improving the Army's data handling capabilities in various reconnaissance and tracking missions, leveraging optical fiber technology for superior energy efficiency and data rates. Interested parties can submit Phase I proposals with a funding limit of $250,000, due by June 25, 2025, with the opportunity opening on May 28, 2025.
