DIRECT TO PHASE II: Resonant Cavity Infrared Detector Incorporating an Avalanche Photodiode Active Region
SBIR Opportunity Analysis
The Department of the Navy is seeking a Direct to Phase II SBIR solution to develop and demonstrate highly sensitive mid-wave infrared detectors that combine resonant cavity infrared detector technology with avalanche photodiode active regions. The work calls for prototype APD-based RCID arrays with multiple wavelength-tuned elements on a single substrate, integrated electrical contacts, test structures, and cooling provisions, with four prototypes to be produced, tested, and delivered to the Naval Research Laboratory. The effort emphasizes wavelength selection across the usable MWIR band, excluding atmospheric absorption regions, and a sensitivity improvement of at least two orders of magnitude over state-of-the-art nBn detectors; work may become classified and requires a U.S.-owned and operated performer able to maintain secret clearances. Applications are due June 24, 2026 at 4:00 PM UTC, and Phase I proposals will not be accepted.
