| 摘 要： | 报道了对几种掺杂SiO2石英系单模光纤的背向受激布里渊散射(BSBS)谱的实验结果,结果表明其布里渊散射斯托克斯频移主要取决于纤芯的掺杂材料和浓度,进一步分析证明了光纤掺杂后将主要通过调制杨氏模量的变化,从而导致BSBS频移量减小.

| Abstract: | In this paper,it describes the experimental result of backward stimulated Brillouin scattering (BSBS) spectra in the doped silica core single-mode fibers,It is indicated that the Brillouin Stokes f-shift depend on the core dope materials and their concentrations,This result also testifies that the variation of Young’s modulus is caused by doped,silica core single mode fiber,and lead to the reduction of BSBS f-shift. |

| Keywords: | Doping fiber BSBS Brillouin f-shift Young’s modulus |
