These emerging industry products have a huge demand for new high-sensitivity laser pointer detectors, and the application of avalanche photon detectors will achieve a revolutionary breakthrough. Harbin Institute of Technology Watson Electronics Co., Ltd. project team relies on Harbin Institute of Technology’s research foundation in the field of semiconductor optoelectronic detection for many years, starting from 2013 after more than three years of pilot research and development, launched a variety of innovative avalanche photon detectors, applied for ten National patents on several related technologies.
Among them, the silicon-based near-infrared micropixel avalanche photon detector was successfully developed for the first time in China, which not only filled the gap of high-sensitivity avalanche photodetectors, but also made Watson Corporation one of the few companies in the world that can produce this device. One of the companies. It is understood that this achievement achieves the detection of weak photons and a greater internal gain through an innovative process combining optimized bipolar semiconductor processes, and avoids the noise problem caused by external amplifier circuits in traditional photodetection devices.
The avalanche photodetector structure and process design are independently developed and produced by mature semiconductor manufacturing processes, which are easy to mass-produce and compatible with CMOS processes. They can replace high-priced foreign similar products and fill domestic product gaps. The person in charge of the project introduced to the reporter that for the future market, the in-depth demand of the laser pointers detection band from visible light to mid-far infrared detection.
