Light Beam Propagation in Twisted Nematics Nonlinear Waveguides

Abstract

In the paper, the light beam propagation in twisted nematic liquid crystalline waveguides is analyzed theoretically. It is shown that optical reorientational nonlinearity in analyzed waveguides is large enough to observe spatial solitons formation with milliwatts of light power. The reorientational nonlinearity induces self-focusing and changes the direction of propagation of the light beam.
