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.
