Research Institution
The objective of this topic is to develop an optimized SLS-based Infrared FPA for high temperature operation with considerations for lower cost, size, weight, and power (C-SWAP). Infrared imaging systems in use today come at a high cost, require large amounts of space, are heavy, and consume large amounts of power. To reduce noise and improve responsitivity, such detectors are cryogenically cooled to below -200 degrees C, which in combination with C-SWAP requirements greatly limit their applicability for integration into aircraft. Detector structures composed of SLS material have demonstrated the potential to achieve high temperature operation MWIR and LWIR, responsivity similar to HgCdTe detectors, and reduced dark currents. We have incorporated several improvements into standard ROIC designs to specifically optimize them for use both MWIR and LWIR SLS detector technologies. Prototypes of the SLS-optimized ROIC will be fabricated, hybridized with a detector array, and tested. BENEFIT: It is anticipated that the Phase II program will result in the fabrication of a SLS-optimized ROIC that will be hybridized with a detector. It is expected that this will result in focal plane array with superior capabilities in terms of high temperature operation, responsivity, and reduced dark currents for insertion into both MWIR and LWIR imaging systems on multiple surveillance, threat warning, and situational awareness platforms. Additional benefits will include the reduction of CSWAP. It is anticipated that the SLS FPA technology will have applicability in locating and tracking individual targets, maintaining track through obscurants, simultaneous targets, and navigation tasks, in both government and commercial sectors, thus providing a dual use.
