Title: Multi-Modal LWIR/VLWIR Focal Plane Array
Agency / Branch: DOD / MDA
Contract: F2960103M0246
Award Amount: $70,000.00


We propose to optimize the design of a highly versatile active/passive multi-color focal plane array (FPA). The device integrates, within a single pixel, both avalanche photodiode (APD) and two-color LWIR/VLWIR sensing capabilities. The design is based onwell proven HgCdTe heterostructure techniques and manufacturing methods.In Phase I, we will investigate both two-terminal and three-terminal, back-to-back photodiode configurations for sequential-simultaneous active/passive dual-band infrared imaging. Using advanced TCAD tools, we will optimize the design of theactive/passive, multi-wavelength infrared HgCdTe semiconductor image sensor to enable high-performance, high-pixel-density focal plane arrays to be manufactured, with high yields, and in a cost effective manner.By using common optics, electronics, and cryo-cooling, monolithically integrating a 3D LADAR imager with a two-color IR imager, in a single focal plane array, offers enhanced target acquisition, discrimination, and aimpoint selection, while reducing EKVmass, volume, and power budgets. The market for non-defense based IR photo-detectors is expected to grow rapidly over the next 10 years. The characteristics that make multi-color IR photo-detectors suitable for defense applications also benefit many industrial and scientificapplications. Several applications include: environmental monitoring, ladar, chem./bio. hazard detection, IR spectroscopic applications in medicine and science, dual band tomographic non-destructive test, remote sensing, and thermography.
