Optomechanics of liquid crystals for dynamical optical response of photonic structures

preprint2010arXivOpen access

Abstract

We show that the mechanical effect of light on the orientational ordering of the crystalline axis of a mesophase can be used to control the dynamics of the optical response of liquid crystal infiltrated photonic structures. The demonstration is made using a one-dimensional periodic structure whose periodicity is broken by the presence of a nematic liquid crystal defect layer. In this study we report on output light polarization and/or intensity dynamics that depends on the initial molecular ordering and incident light wavelength and intensity.
