ABSTRACTIn this report, we describe the photo-induced in-plane alignment of nematic liquid crystal (LC) molecules, 5CB, in a hybrid cell with alternate self-assembled films of low-molecular weight azobenzene dye and polyelectrolyte on gold electrodes using the attenuated total reflection (ATR) measurement method. The molecular self-assembly process was also investigated by the ATR method. Reflectivities due to excitations of the surface plasmon polariton (SPP) were observed in the ATR properties of the LC cell. In-plane switching of the LC molecules adjacent to the aligning layer was evaluated from the ATR curves after irradiation of linearly polarized visible light to the LC cell. The sensitivity of the ATR method gives information on the alignment, tilt angle, and extent of LC reorientation in the bulk. Thus, the importance of using the molecular self-assembly processes of individual polyion-dye pairs for fabrication of new photo-aligning layers is emphasized.

Semi-circle long-range dielectric-loaded surface plasmon-polariton waveguide (LR-DLSPPW) is proposed, in which a thin and narrow metal stripe (15-nm-thick and 500-nm-wide) is sandwiched between a semi-circle dielectric ridge(with the refractive index of 1.535 ,the radius of 777 nm) and a dielectric film (with the refractive index of 1.493) supported by low-index substrate (with the refractive index of 1.34). The mode effective index, propagation length, mode width and figures of merit of the fundamental mode supported using the finite-element method are calculated at the telecom wavelength λ =1.55μm for different dimensions (t) of the dielectric film. It was calculated that the optimized structure have the maximized parameters with figures of merit 3.75×10¬6and propagation length 3.7mm at t=570 nm. The semi-circle LR-DLSPPW structure is found to exhibit about 20% increase of the propagation length as compared to the conventional rectangular LR-DLSPPW while ridge thickness t≤600 nm. The proposed configuration allows for easy connection to electrodes enabling, and is technologically simple being compatible with planar fabrication using UV-lithography.
