Ferroelectric liquid crystals (FLCs) can provide fast electro-optic switching effects in photonic crystal fibers, which are promising for developing integrated optical modulators to be used for optical telecommunication. The present study describes experiments on capillaries filled with FLCs, which pave the way toward application of FLCs in state-of-the-art solid core microstructured optical fibers. A method to achieve uniform alignment of the helix axis and the appearance of two different switching modes with switching times in the submillisecond range are found. An additional slow relaxation that was reported recently can be attributed to space charge fields, which may appear due to the migration of ions.

We report the deposition of Langmuir-Blodgett (LB) thin films of low-weight dispersed composite systems of ferroelectric liquid crystals (FLCs)-functionalised silver (Ag) nanoparticles. Because of their amphiphilic nature the molecules form stable Langmuir monolayers, which were transferred to silicon substrates. We noticed that absorption wave numbers are present for each bond constituting FLC-nanoparticles composite system, ensuring a complete transfer of molecules from water sub-phase. XRD showed intense peaks at 2θ = 3.2°due to the layer structure of FLC molecules. We infer from the morphology of LB films that doping of nanoparticles do not provide any hindrance to SmC Ã layer structure of FLC molecules. The photoluminescence study indicates blue shift in emission spectra and peak intensity increases with Ag nanoparticles concentration. ARTICLE HISTORY
