Topic:
QPD-Based Room-Temperature Broadband Infrared Photodetectors for Next-Generation Smart Sensing
Abstract:
IR Vision develops high-sensitivity photonic infrared sensors based on a novel quasi-photo-Dember (QPD) photodetection mechanism. Unlike conventional photonic infrared detectors that often require external bias and cooling systems, our first-generation InAs infrared detector enables intrinsic photodetector gain under zero-bias operation and delivers high-performance room-temperature detection. The technology supports an ultra-broad spectral response from 400 nm to 3.5 μm, covering visible, near-infrared, short-wave infrared and mid-wave infrared wavelengths on a single chip. By combining high sensitivity, low power consumption, compact form factor and cost-effective manufacturability, IR Vision aims to address the size, weight, power, performance and cost limitations of existing infrared sensing solutions. This technology will enable high performance requirement, cost constrained applications including UAV heat-source detection, gas and water-quality monitoring, spectroscopy and smart sensing in the future.
