Research Progress on Fabrication and Application of Mid-Infrared Glass Fiber Gratings
The mid-infrared band contains extremely important atmospheric infrared windows and the fingerprint regions of many important molecules. The light sources and optical devices in this band have important applications in the fields of optoelectronic countermeasures, environmental monitoring, biological sensing, and medical diagnosis. As a key component of all-fiber mid-infrared lasers, mid-infrared glass fiber gratings have become a recent research hotspot. Fluoride fiber gratings, chalcogenide fiber gratings, and tellurite fiber gratings are the most widely used mid-infrared glass fiber gratings. This paper gives a comprehensive and systematic overview of the performance characteristics, fabrication process, research status, and application fields of the three kinds of fiber gratings, and analyzes the advantages and limitations of the current mid-infrared glass fiber gratings. It provides a reference for further improving the performance of mid-infrared fiber lasers and expanding the application field of mid-infrared fiber gratings.
