掺铋光纤的历史、发展和展望

History,Development and Outlook of the Bismuth-Doped Optical Fibers

回顾并总结了掺铋光纤的历史和发展,2005年在世界上首次采用MCVD技术研制出了掺铋光纤。为了在宽的光谱范围内获得掺铋光纤激光器和放大器,对不同组分玻璃纤芯的掺铋光纤进行了深入研究。报道了石英基玻璃掺铋光纤、锗酸盐玻璃掺铋光纤、硅锗酸盐玻璃掺铋光纤、铝硅酸盐玻璃掺铋光纤以及硅磷酸盐玻璃掺铋光纤。通过上述研究,在1150~1800 nm范围内实现了一系列铋掺杂的光纤激光器和放大器。

The presentation includes brief information concerning the Fiber Optics Research Center of the Russian Academy of Sciences.The results on the research and development of Bismuth-doped(Bi-doped)optical fibers,Bi-doped fiber lasers and optical amplifiers are discussed in detail.The first Bi-doped optical fibers were fabricated by the Fiber Optics Research Center together with the Institute of High-Purity Substances in 2005 using MCVD technique.To create Bi-doped fiber lasers and optical amplifiers operating in broad spectral region,it is necessary to use Bi-doped fibers with various core glass compositions.We selected the following fiber core glasses:Bi∶SiO2,Bi∶GeO2,Bi∶GeO2-SiO2,Bi∶Al2O3-SiO2,Bi∶P2O5-SiO2.In the results,a family of Bi-doped fiber lasers and optical amplifiers operating in the spectral region 1150~1800 nm is developed.
