Abstract
Optical reorientational nonlinearity in twisted nematic liquid crystalline planar waveguide is analyzed theoretically. It is shown that optical nonlin earity for guided modes in analyzed waveguides can be approximated by satur ation nonlinearity. Predicted nonlinearity is large enough to observe effec ts like spatial solitons formation with milliwatts of light power.
