摘要

本文利用RSoft Fullwave软件对二阶圆柱矢量光束在梯度折射率和微结构光纤中的传播进行了数值模拟。二阶矢量光束显示为这些光纤的矢量模式。在计算的基模中，发现存在与光束传播方向相反的能量流的区域(反向能量流区域)。反向能量流纵向分量的绝对值远低于正向能量流的绝对值。

Reverse energy flow in vector modes of optical fibers

In this paper, the propagation of a second-order cylindrical vector beam in gradient-index and microstructured fibers is numerically simulated using the RSoft Fullwave software. The second-order vector beams are shown to be vector modes of these fibers. In the calculated fundamental modes, regions are found in which there is an energy flow directed oppositely to the beam propagation direction (regions of a reverse energy flow). The absolute value of the longitudinal component of the reverse energy flow is found to be much lower than that of the forward flow.
