Monolithic SiGe SWIR Imaging Cameras

In this project, Agiltron and RTI International propose to demonstrate low-cost, low-power, man-portable megapixel SiGe SWIR imaging cameras as a vehicle to replace more costly InGaAs imaging cameras. In Phase I, superlattices of Ge quantum dots or strained SiGe layers will be investigated for their detection performance in the SWIR band. In Phase II, leveraging the colossal investments made in the Si CMOS microelectronics industry, Agiltron and RTI will transition the proposed SiGe technology to fabricate two-dimensional FPAs with SiGe photosensitive areas monolithically integrated with Si CMOS ROIC, thus eliminating the hybrid approach of conventional InGaAs FPAs. The SiGe FPAs will be packaged into fully functional imaging cameras using Agiltron’s proficiency in optoelectronic module design, assembly, and manufacturing. The SiGe SWIR imaging cameras produced under this project will possess unprecedented price/performance metrics, and the low cost will enable widespread adoption by the military and commercial markets and open up new, disruptive markets.
