Optical-Surface Guided-Waves in Chiral Liquid-Crystal Films
TLDR
In this paper, the surface guided electromagnetic wave (SGEW) excitation by a beam incident at a CLC film from the side of a boundary without total internal reflection (TIR) is investigated.Abstract:
Excitation of Surface guided electromagnetic waves (SGEW) of optical wave range in chiral liquid crystals (CLC) are theoretically examined in the framework of dynamical diffraction theory. In contrast to the traditionally discussed method of SGEW excitation by means of attenuated total external reflection (ATER) the SGEW excitation by a beam incident at a CLC film from the side of a boundary without total internal reflection (TIR) is investigated. In the general case an analytical description of the SEW excitation can not be carried out. It is why the limiting case allowing simplification of the problem, namely, SGEW of the second order diffraction. is examined in details.read more

TL;DR: In this article, the dispersion equations are obtained and analyzed for SGEW in the second order diffraction in cholesterics and the dependence of SGEW penetration on the frequency and propagation direction is investigated, and it is shown that two of the four different SGEW modes have unusual polarization properties changing with the SGEW frequency.
