摘要

利用矢量有限元法，数值模拟了不同结构参数下光子晶体光纤中空气孔填充率与去极化型声波导布里渊散射频移的关系，以及布里渊散射频移与布里渊散射效率的关系。研究结果表明，空气孔填充率的增大会导致扭转径向模式的去极化型声波导布里渊散射频移下移。空气孔节距或纤芯直径一定时，高阶模式的频移对空气孔填充率的变化更为敏感。扭转径向模式的去极化型布里渊散射效率都随布里渊散射频移的增大而增大。

Abstract

The influence of the air hole filling factor on the frequency shift of depolarized guided acoustic Brillouin scattering in photonic crystal fibers with various structural parameters was presented. The dependence of Brillouin frequency shift on Brillouin scattering efficiency was investigated. The results indicate that the Brillouin frequency shift decreases with the air hole filling factor increasing. For a given lattice pitch or core diameter

the influence of the air hole filling factor on frequency shift of the higher order torsional-radial mode is more sensitive

and the scattering efficiency of the depolarized guided acoustic Brillouin scattering increases with the Brillouin frequency shift increasing.
