Abstract:

Liquid Crystals (LCs) are well-known “smart” materials combining self-organizing properties with fluidity and being responsive to a wide variety of external stimuli. New generation photonic devices can be realized exploiting unique properties of LCs. We will present achievements in plasmonics and optofluidics. Reconfigurability of LCs was employed in “Active Plasmonics” devices where the plasmonic resonance of gold nanoparticles (GPNs) could be finely controlled by means of external perturbations (electrical field, light, temperature). For the first time, the LC alignment was controlled by external pressure enabling of a peristaltic optofluidic modulator.
