(Received 25 March 2008; accepted 30 April 2008; published online 22 May 2008)

We report on the experimental studies of the light-induced reorientational effects in a one-dimensional periodic photonic structure with an embedded planar nematic-liquid-crystal defect. We demonstrate that in the presence of a periodic structure, the self-action of light in a liquid-crystal layer demonstrates sharp power-dependent characteristics for the intensity-dependent optical transmission. Robustness of the effect suggests its applications for all-optical tunable photonic devices.

FIG.1
(a) Schematic of the one-dimensional periodic structure with a liquid-crystal defect layer. (b) shows a sketch of molecular alignment in the liquid crystal; schematically shown molecular reorientation in the (x,y) plane; θ is the orientational angle, β is the angle between the direction of the electric field and the y coordinate. (c) Experimental (red) and theoretical (blue) transmission spectrum of the periodic structure with LC defect layer. (d) Zoom of the theoretical spectra near the pumping wavelength λ = 532 nm showing the existence of ordinary (β = 0°) and extraordinary (β = 90°) defect modes. In addition to this, we plot the variation of the transmission after reorientation, by assuming that Θ(z) = Θmax sin(πz/L).

Experimental setup: M, mirrors, λ/2, waveplate, P, polarizer, L, lens, A, analyzer, S, screen, D, detector, and CCD camera. Linearly polarized light after polarizer and waveplate is focused on the front facet of the structure by means of lens with f = 100 mm. Polarizer and waveplate allow to control the polarization and input power.
