AbstractAerius Photonics proposes to develop photon-counting, linear-mode detection, active imaging focal plane arrays (FPAs) with photoresponse from 0.4 to 2.5 μm wavelength (VIS-NIR-SWIR) by inserting their BroadwaveT photodetector material into an Avalanche Photodiode (APD) structure. In Phase I Aerius will demonstrate the feasibility of the approach by fabricating APD arrays and test structures with photoresponse to 2.1 μm, and develop a Readout Integrated Circuit (ROIC) design appropriate to work with the APD arrays. In Phase II Aerius will fabricate 256x256 APD arrays with photoresponse to 2.5 μm, complete the design of and fabricate an appropriate ROIC, integrate the detector arrays with ROIC and demonstrate active imaging with the FPA throughout the VIS-NIR-SWIR wavelength bands.
