Polarization-Independent Adaptive Lens With Two Different Blue-Phase Liquid-Crystal Layers

An adaptive microlens structure is proposed using two polymer-stabilized blue-phase liquid-crystal layers whose Kerr constant is largely mismatched. This device exhibits several favorable features, such as polarization independence, simple structure, and good parabolic phase profile. Its applications for 2D/3D switchable displays and other photonic devices are emphasized. © 2013 Optical Society of America
