Abstract

Bismuth-doped phosphosilicate fibers have become the most promising gain medium for O-band amplifiers. Yet scientific challenges on understanding the nature of bismuth active centers (BACs), mechanisms of bismuth cluster formation in the phosphosilicate glass network still exist. It is likely that multiple BACs with different oxidation states in different structural sites all contribute to the broad, nonsymmetric luminescence and gain spectra. Due to the progress in the fundamental understanding of bismuth-doped phosphosilicate glass, various designs of optical amplifiers with decent performances have been demonstrated.

O波段光放大器用掺铋光纤综述——科学挑战与展望

掺铋磷硅酸盐光纤已成为o波段放大器中最有前途的增益介质。然而，在理解铋活性中心(BACs)的性质、磷硅酸盐玻璃网络中铋团簇形成的机制方面仍然存在科学挑战。在不同的结构位点上具有不同氧化态的多个bac可能都导致了宽的、不对称的发光和增益光谱。由于对掺铋磷硅酸盐玻璃的基本认识的进步，各种性能良好的光放大器的设计已经被证明。

期刊介绍： The International Journal of Applied Glass Science (IJAGS) endeavors to be an indispensable source of information dealing with the application of glass science and engineering across the entire materials spectrum. Through the solicitation, editing, and publishing of cutting-edge peer-reviewed papers, IJAGS will be a highly respected and enduring chronicle of major advances in applied glass science throughout this century. It will be of critical value to the work of scientists, engineers, educators, students, and organizations involved in the research, manufacture and utilization of the material glass. Guided by an International Advisory Board, IJAGS will focus on topical issue themes that broadly encompass the advanced description, application, modeling, manufacture, and experimental investigation of glass.
