Research progress on luminescence mechanism of bismuth active center in Bi-doped optical fiber |
| |
Abstract: | Bi-doped optical fibers have broad application prospects in fiber amplifiers and lasers due to the unique luminescence characteristics. In order to understand the luminescence mechanism of Bi-doped optical fiber and develop the Bi-doped material with high-efficiency and high-performance, the research achievements in the luminescence mechanism of Bi-doped optical fiber were summarized. Based on the atomic structure and luminescence characteristics of bismuth active centers(BAC), the authors summarized the relationship between different structures and luminescence wavelength in Bi-doped optical fiber. Due to their advantages of long fluorescence life and wide spectral range, Bi-doped materials are expected to be more widely used in the fields of ultra-wideband light sources, ultra-wideband amplifiers, tunable lasers, and so on. |
