研究了具有无限均匀各向同性包层的圆柱向列液晶波导。控制波传播的液晶核的介电张量由向列指向器的构型决定。传播光场可以改变定向器的结构,从而改变介电张量。我们使用一个迭代的数值格式来确定传播常数作为光功率的函数。
A cpylindrical nematic liquid-crystal waveguide with an infinite homogeneous isotropic cladding is considered. The dielectric tensor of the liquid-crystal core that governs wave propagation is determined by the configuration of the nematic director. Propagating optical fields can alter the director configuration and thus change the dielectric tensor. We use an iterative numerical scheme to determine the propagation constant as a function of optical power.
