Abstract
Theoretical analysis indicates that resonant infrared photoconductors can achieve unit quantum efficiency at resonant frequencies. This concept, which is based on establishing a resonant absorption cavity internal to the detector element, offers numerous other enhancements and advantages over conventional detectors. Here, we present an overview of the operation of the device and outline the fabrication process of a Ge:Ga far-IR photoconductor. The preliminary test results performed on a prototype Ge:Ga detector show the expected resonant fringes with enhanced response. The summary of the results and the status of the project will be discussed.
