Liquid-Crystal Optical Waveguides

  • D. J. Channin

Abstract

In recent years a new optical technology has developed in the field of light guiding in thin films and fibers. Liquid-crystal materials have yet to contribute to this technology to the extent that they have to display devices and optical beam processing; nevertheless, examples of liquid-crystal waveguide modulators,1,2 switches,3 and deflectors4 have been demonstrated. Furthermore, optical waveguiding holds potential as a tool for investigating physical and chemical processes in thin films,5 including liquid crystals.
