Numerical simulation of laser beam interaction with a liquid crystal medium in a miniature fiber-optical system

摘要: Laser beam propagation through an integrated fiber-optical system including a miniature cavity filled with liquid crystal (LC) is numerically simulated. Two different shapes of the are considered: transverse cylindrical hole and gap between parallel end faces optical fiber. In both cases, director field distribution in LC volume includes linear singularity (disclination). The Maxwell equations for anisotropic continuous medium solved by FDTD method. Nonlinear effects interaction ignored. simulations provide data on intensity direction laser that passed microscopic volume. portions radiation lost due to scattering into ambient remaining inside fiber calculated. Based calculations, it may be concluded significant fraction energy case shaped as scattered owing foc...
