Quantum Waveguide Infrared Photodetector for Heterodyne Spectroscopy

EMode Photonix proposes to develop a novel, room-temperature Quantum Waveguide Infrared Photodetector (waveguide-QWIP), based on NIST Patent No. US 11,271,023, to advance heterodyne spectroscopy for precise gas detection and distinction. Current mid-infrared detectors often require cryogenic cooling, limiting their practicality for portable and space-based applications. Our waveguide-QWIP technology will enable high-speed, low-noise detection at room temperature, facilitating the development of compact, integrated systems. This Phase I program will focus on the design, fabrication, and experimental validation of prototype detectors, specifically targeting the detection and distinction between methane and ethane using heterodyne spectroscopy. By eliminating the need for cryogenic cooling and demonstrating high performance in targeted gas detection, our innovation will unlock new possibilities for environmental monitoring, industrial process control, and remote sensing. This advancement directly supports NASA's mission for advanced sensing technologies and will drive significant economic benefits through commercialization.
