Advanced Infrared Emitter Array (AIREA)

ABSTRACT: We propose build Infrared LED (IRLED) scene projectors that are able to project larger than 1k by 1k imagery with maximum temperatures of 3000K, frame rates in excess of 400 Hz, and emission wavelength between 3-5 microns. We will explore the use of through-silicon-via (TSV) and silicon interposer packaging technologies to achieve that goal. We will also evaluate the performance and cost tradeoffs involved in using the established 48 um pixel pitch versus scaling down to 24um pixel pitch for both IRLED arrays and CMOS Read-In Integrated Circuits (RIICs). Our team consists of experienced IRLED fabrication experts, RIIC designers, and packaging specialists. BENEFIT: Infrared LED (IRLED) arrays represent a potentially game changing technology for presenting infrared images in sensor ground test environments offering high frame rate and high temperature simulation, while achieving superior manufacturing yield and uniformity than competing resistor array technology. The proposed work offers a significant opportunity for achieving near-term breakthrough results in making effective IRLED scene projectors by developing areas of IRLED technology that have not been previously addressed.
