Polarized light in anisotropic medium with twisting

Abstract

Abstract⎯The evolution of state of light polarization in a smoothly inhomogeneous anisotropic medium is analyzed both theoretically and experimentally. The analytical expressions describing the polarization state in such a medium are obtained. In particular, the results of analysis are applicable to a nematic liquid crystal with twist orientation. It is shown that although the polarization state, when light propagates in such a medium, undergoes oscillations, spatial frequency of which depends on the thickness of the sample, nevertheless, the phenomenon of adiabatic tracking is observed at the exit in the case of both input e and o waves. The experiments confirm the results of theoretical analysis.

Пространственная Динамика Вектора Квазиспина Света В Анизотропной Среде С Кручением

“…Целью настоящей работы является теоретическое рассмотрение пространственной эволюции состояния поляризации света в анизотропной среде с кручением локальной оптической оси и с примесью гиротропных молекул. Основой анализа является система уравнений связанных волн, полученных в приближении геометрической оптики, и их решение посредством перехода во вращающуюся систему координат [17,18].…”

Spatial dynamics of light quasispin vector in an anisotropic medium with twisting

“…The objective of this paper is to theoretically consider the spatial evolution of the light polarization state in the anisotropic medium with twisting of he local optical axis and admixture of gyrotropic molecules. The basis for the analysis refers to a system of coupled-wave equations obtained in the approximation of geometrical optics, and their solution by transition into rotating coordinate system [17,18].…”
