Research progress of mid-infrared quantum spectrum transfer and its application
Traditional mid-infrared detection is mainly based on narrow bandgap material detectors such as mercury cadmium telluride,but the high sensitivity detection of such detectors requires deep cooling equipment,and there is a significant performance gap compared to mature silicon-based detectors.Mid-infrared quantum spectrum transfer can upconvert mid infrared signals to the operating band of silicon-based detectors for efficient detection using high-performance silicon detectors.This technology can also down convert signal photons to the mid-infrared band and fully preserve photon information during the conversion process,playing an important role in the field of mid-infrared quantum light field generation and regulation.This article systematically introduces the basic principles,main parameters,and latest research progress of mid-infrared quantum spectrum transfer,and prospects its application prospects and research directions.
