AbstractTwo-dimensional (2-D) infrared (IR) emitter arrays are of great importance in numerous military and commercial applications, including IR scene generation and infrared detection system emulation for missile warning systems (MWS), IR radiometric duplication and counter measurement, and medicine and spectroscopic trace-gas sensing. Existing technologies are limited in array size, dynamic range, speed, and emission IR bands that can be generated. This SBIR Phase I proposal aims to develop a new type of high-speed emitter array capable of two-color IR generation with a large dynamic range. Successfully developing the proposed innovation is expected to provide an enabling technology for high-speed IR scene projection with large dynamic coverage and voltage-tunable IR emission bands. In this SBIR phase I project, a preliminary 2×2 infrared (IR) emitter array will be developed for proof-of-concept demonstration. Performance features, such as multi-spectral emission, high-speed modulation and large dynamic range will be characterized and demonstrated. A large format (1024×1024) emitter array will be demonstrated and delivered to Air Force research lab in Phase II.
