34.2: Invited Paper: Active Plasmonic, Tunable Metamaterials and Ultrafast Nonlinear Optics with Liquid Crystals

Iam Choon Khoo

Abstract: NLC have been incorporated in a multitude of novel structures such as photonic crystals, waveguides and plasmonic and metamaterials nanostructures to enable dynamical control of light transmission. A critical review of the underlying nonlinear optical responses of nematic as well as Blue-Phase liquid crystals is presented.

The need for thin active metasurface based elements, opens an exciting research direction toward exploration of various active materials and their control mechanisms. Here, an all-optical control mechanism of composite metasurfaces is studied, based on rapid laser-induced thermo-optical nonlinearities in nematic liquid crystals (NLCs). Specifically, the absorption of photons leads to local heating, which in turn facilitates a nematic-to-isotropic (N-I) phase transition of a twisted-NLC (TNLC) layer that is sandwiched between an indium tin oxide (ITO) coated glass plate and the metasurface. This mechanism is used to experimentally demonstrate all-optically switchable plasmonic metasurface color tag. The dependence of the switching on the laser power and the dynamic response of the device are characterized. Experimental results show that the pump beam power significantly affects the switching time, which can be further reduced by thermal management of the design. Such switching mechanisms have great potential in all-optically controlled systems and can be applied to realize additional active and multifunctional optical devices at nanoscale.
