We demonstrate experimentally that a one-dimensional photonic crystal with a homeotropic nematic liquid crystal defect behaves as a polarization-sensitive nonlinear all-optical device. We study statics and dynamics of the nonlinear optical response for linearly and circularly polarized beams and show enhanced light sensitivity and polarization self-modulation effects
