We report on a novel nanoinjection-based short-wave infrared imager, which consists of InGaAs/GaAsSb/InAlAs/InP-based nanoinjection detectors with internal gain. The imager is 320×256 pixels with a 30-m pixel pitch. The test pixels show responsivity values in excess of 2500 A/W, indicating generation of more than 2000 electrons/photon with high quantum efficiency. This amplification is achieved at...
