摘要

采用改进的化学气相沉积技术结合液相掺杂工艺制备了低损耗Bi掺杂高磷石英基光纤，P

摩尔分数高达7.2%，光纤的背景损耗为18 dB/km@1 550 nm。进一步采用1 240 nm的可调谐拉曼激光器泵浦自制Bi掺杂高磷石英基光纤，在1 355~1 380 nm波段实现净增益，在1 355 nm波长处的最高增益为5.14 dB。这是国内首次制备出低损耗掺铋高磷石英基光纤，并基于该掺铋光纤实现了近红外波段的净增益放大。

Abstract

The low-loss bismuth- and highly phosphorous-co-doped silica fiber(BPDF) was prepared by the modified chemical vapor deposition technology combined with the solution doping method

where the mole fraction of phosphorous was as high as 7.2% and the background loss was 18 dB/km@1 550 nm. We used the tunable Raman laser operating at ~1 240 nm to pump the homemade BPDF

and achieved a broadband amplification in the range of 1 355 nm to 1 380 nm. The proposed BPDF amplifier provided the maximum gain of 5.18 dB at 1 355 nm. To our knowledge

this is the first report on the realization of low-loss BPDF fabrication

and the broadband amplification in the near-infrared band using the homemade BPDF in China.
