Progress in Preparation and Applications of Low-Loss Chalcogenide Infrared Fibers

硫系玻璃具有红外透过范围宽、非线性系数高、易光纤化等特点,在中红外光子集成、光纤光源、传感等光学领域极具应用前景。随着红外光学的发展,硫系玻璃及其光纤研究取得了许多进展。为此,综述低损耗硫系玻璃光纤制备及其在光纤器件(耦合器、合束器、传像束和光纤光栅)和光纤光源、光纤传感等方面的研究进展,分析存在的问题,并展望未来发展方向。

Due to the characteristics of wide mid-infrared transmission range, high non-linear coefficients, and easily fiberized performance, chalcogenide glass has very important applications in mid-infrared photonic integration, optical fiber source, sensing, and other optical fields. In recent years, with further development of the infrared optics, some progresses have been made in the research of chalcogenide glasses and their optical fibers. From this point of view, the research progress of the fabrication of low-loss chalcogenide fiber, and its application fields including fiber devices (couplers, combiners, bundles, and fiber gratings), fiber-based light sources, and optical fiber sensing at home and abroad are summarized in this review. Besides, some existing problems are analyzed and the future development direction is prospected.
