Completed Technology Project

Project Introduction

Photonic antenna coupled middlewave infrared photodetector and focal plane array with low noise and high quantum efficiency, Phase I
Middle-wave infrared (MWIR, 3-5 µm) photodetectors are of great importance in numerous NASA applications, including thermal remote sensing for carbon-based trace gases (CH4, CO2, and CO), heat capacity mapping for earth resource locating, environment and atmosphere monitoring, and IR spectroscopy. However, existing MWIR photodetectors are require a low operating temperature, below 77K to achieve high photodetectivity (D*). More »
