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.
Dr. Luciano De Sio graduated in Physics at the University of Calabria in 2003 and obtained his Ph.D in Science and Technology of Mesophases and Molecular Materials from the University of Calabria in 2006. His scientific research interests and expertise are in the fields of optics of liquid crystals, holographic diffraction gratings, optofluidics and plasmonics. He has co-authored 50 articles, over 20 scientific communications at conferences and co-authored three international patents.
