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.
