论文摘要
这项研究研究了两种双模式双纤维的六个极化模式之间的非线性频率转换。目的是证明在泵波长处线性极化空间模式的不同组合的选择性激发会启动不同的模式间矢量四波混合过程。特别是，这项研究表明，令人兴奋的两个正交偏振的LP01和LP11模式可能会导致在不同波长下同时生成多达三对不同空间模式的正交极化。说明了空间模式的相位双折射在这种四波混合过程的相匹配中的作用。此外，通过基于耦合的非线性schrodinger方程的数值模拟来验证理论预测，并在市售的双向纤维中进行了实验证实。
This study investigated the nonlinear frequency conversions between the six polarization modes of a two-mode birefringent fiber. The aim was to demonstrate that the selective excitation of different combinations of linearly polarized spatial modes at the pump wavelength initiates distinct intermodal vector four-wave mixing processes. In particular, this study shows that exciting two orthogonally polarized LP01 and LP11 modes can result in simultaneous generation of up to three pairs of different spatial modes of orthogonal polarizations at different wavelengths. The role of the phase birefringence of the spatial modes in the phase-matching of such a four-wave mixing process was explained. Moreover, the theoretical predictions were verified through numerical simulations based on coupled nonlinear Schrodinger equations and also confirmed experimentally in a commercially available birefringent fiber.
