摘　　要：掺稀土光子玻璃在光纤通信、激光雷达、远程遥感、红外探测以及生物医疗等领域有着重要的应用前景.目前,所广泛采用的石英基光子玻璃存在稀土掺杂量低、发光带宽窄、声子能量大和增益系数低等本征因素,制约着相关材料和元器件的发展.因此,研究和发展新型光子玻璃和光纤以适应新波段尤其是近中红外材料与器件的需求非常必要.本文概述了掺稀土光子玻璃在光纤放大器和光纤激光器中的重要应用,归纳了实现近中红外发光与激光对稀土离子和基质材料的基本要求,重点阐述了发射波长在1.0,1.5,2.0和3.0?m波段掺稀土光子玻璃及光纤与元器件的最新研究进展,指出了掺稀土光子玻璃近中红外发光与激光所面临的挑战,对其未来的应用和发展方向做出了展望.Rare-earth（RE） doped photonic glasses exhibit potential applications in the area of optical communication, laser lidar, remote sensing, infrared detection, and biomedical. Up to now, the widely used silica based photonic glasses encounted intrinsic limitations such as lower rare-earth doping concentration, narrower emission band, larger phonon energy, and lower gain coefficients. Therefore, it is necessary to study and develop novel photonic glasses and fibers to meet the needs of new wavelength bands, especially the near- and mid-infrared materials and devices. In this paper, the important applications of RE doped photonic glasses in optical fiber amplifiers and fiber lasers are briefly described. The basic requirements for realizing near- and mid-infrared luminescence and laser are summarized. The latest research progress in RE doped photonic glasses, fibers, and devices are reviewed with special emphasis on 1.0, 1.5, 2.0 and 3.0 μm wavelength bands. In addition, challenges, applications, and future advances of the near- and mid-infrared luminescence and laser in RE doped photonic glasses have also been dealt with.
