Nonlinear Optics of Electrochromic and Photosensitive Cells of Ionic Liquid Crystals and Mesomorphic Glasses

Abstract

We study structural and nonlinear optical properties of lyotropic ionic liquid crystals with electrochromic impurities and mesomorphic glasses of the homological series of Co alkanoates. Nontraditional nonlinear optical mechanisms of these materials are proposed. The investigated cells are characterized by high value of optical nonlinearity (χ⁽³⁾ ∼ 10⁻⁷–10⁻⁸ esu), fast recording and relaxation of dynamical holographic gratings. They are perspective to applying in high-speed telecommunication systems.
