Abstract

We demonstrate and analyze the acousto-optic coupling between two optical polarization modes of the LP(01) mode propagating in a highly birefringent photonic crystal fiber. The coupling is realized based on wavelength selective acousto-optic coupling by traveling torsional acoustic wave in an all-fiber tunable polarization filter configuration. The dispersion properties of the torsional acoustic wave in the photonic crystal fiber and the influence of axial non-uniformity in the modal birefringence on the filter transmission are discussed in detail.

摘要

我们展示并分析了在高双折射光子晶体光纤中传播的LP(01)模式的两个光学偏振模式之间的声光耦合。这种耦合是基于全光纤可调偏振滤波器配置中传播的扭转声波通过波长选择性声光耦合实现的。详细讨论了光子晶体光纤中扭转声波的色散特性以及模态双折射中的轴向不均匀性对滤波器传输的影响。
