DIRECT TO PHASE II: Resonant Cavity Infrared Detector Incorporating an Avalanche Photodiode Active Region

The DON26BZ02-DV051 program seeks to develop and demonstrate highly sensitive, wavelength-tuned, discrete photodetectors for mid-wave infrared (MWIR) imaging. The objective is to combine resonant cavity infrared detector (RCID) technology with avalanche photodiode (APD) active regions to achieve a minimum two-order-of-magnitude increase in sensitivity over current nBn type detectors. These detectors will offer wavelength selection across the usable MWIR band, excluding atmospheric absorption sub-bands. The project requires the ability to construct multiple RCID-APD detectors with different tuned wavelengths on the same substrate. Phase II involves prototyping and testing these APD-based RCIDs, while Phase III focuses on transitioning the technology to Navy use and scaling it for broader applications in defense, homeland security, NASA, and commercial sectors like materials identification and remote sensing. The project is subject to ITAR and US Export Control Laws, with work potentially becoming classified in Phase II, requiring U.S. ownership and the ability to maintain security clearances.
