Metallic nanowire arrays are created by pumping molten metal into the hollow channels of silica glass PCF. Measurements show that, at certain wavelengths, the core-guided light couples to leaky surface plasmon modes on the nanowires.

Since the first demonstration of four-wave mixing in Kerr nonlinear media, a lot of works have been devoted to the realization of self-pumped phase conjugate mirrors (SPPMC), where a single incident beam generates its own phase conjugate replica through the self-generation of the pump waves. The most popular schemes make use of a photorefractive crystal, either inside a resonator cavity or alone with the pumps contained inside the sample by internal reflection at the crystal faces. Here we show a scheme based on a photorefractive liquid crystal light-valve (LCLV) with tilted feedback mirror. The self-generated waves come from the optical feedback, which induces a self- sustained refractive index grating in the liquid crystal layer.

We have studied the dynamics of the LC in periodic structures for elliptically polarized wave beyond the optical Freedericksz transition. We have shown that if the number of layers is large enough, the static solution will become dynamically stable for the whole range of its existence. In that sense the periodic structure can stabilize the reorientation dynamics. In the periodic oscillation regime the transmission coefficient exhibits sharp dynamical resonances, thus offering a novel and attractive opportunity to design new ail-optically tunable photonic bandgap structures based on infiltrated liquid crystal materials.
