35‐3: Polarization Dependent Switchable Micro‐lenticular Lens Arrays using Optically Isotropic Liquid Crystals

Abstract

We propose polarization-dependent micro-lenticular lens arrays (MLAs) based on optical phase modulation by reorientation of nano-sized LC droplets of the optically isotropic liquid crystals (OILC). On applying gradient in-plane field, the gradient refractive index is generated between the electrodes, giving rise to the MLAs with the focal length of 22 µm at 50 V rms and switching time of few ms. The OILC can also be applied to switchable microlens. The proposed device has a potential to be applicable to 2D/3D switchable optical lens.
