"Novel Infrared Photon Detectors with Extreme Sensitivity"
Abstract: From portable medical tomography to finding Earth-like planets, infrared photon detectors with extreme sensitivity can realize many of our dreams. This talk highlights our recent breakthroughs in increasing the sensitivity of our bio-inspired “Nano-injection Detectors” in the short wavelength infrared (SWIR) region. The physics of operation and the unique properties of this new device are presented. In comparison to the best existing detectors based on other technologies, the Nano-injection detectors show small noise, high internal gain, and excellent ability to form high-resolution cameras with single-photon detection sensitivity above cryogenic temperatures - for the first time. The impact of this technology on some applications, including medical imaging, night vision, quantum computing, and astronomy will be discussed.
