摘要
Ultra-wide spectrum light source plays an important role in large capacity fiber optic communication and fiber optic sensing. This paper designed an Er/Bi co-doped fiber, using a single-layer pumping structure on the performance of the designed fiber, which focuses on the pump power, fiber length on the performance of the output spectrum of Er/Bi codoped fiber. The experiment shows that doping formula of Erbium and Bismuth ions is beneficial to improve the intensity of L band emission line, which provides a basis for further revealing the intrinsic mechanism of Bismuth ions near infrared luminescence center. Finally, a high brightness ultra-wide spectrum light source of S+C+L band from 1450nm to 1700nm is obtained from the study of multi-parameter equalization method, in which 5dB bandwidth reached 105nm in the center of 1550nm wavelength, and the fluorescence intensity showed an upward trend after 1650nm wavelength. It can be seen that this light source will have a promising application prospect in the fields of large capacity optical fiber communication system and large capacity optical fiber sensing system.
