We demonstrate that one-dimensional photonic crystals with pure nematic liquid-crystal defects can
operate as all-optical switching devices based on optical orientational nonlinearities of liquid
crystals. We show that such a periodic structure is responsible for a modulated threshold of the
optical Fréedericksz transition in the spectral domain, and this leads to all-optical switching and
light-induced multistability. This effect has no quasistatics electric field analog, and it results...[Show more]
