Simulation Study on Polarization-Independent Microlens Arrays Utilizing Blue Phase Liquid Crystals with Spatially-Distributed Kerr Constants
Polarization independent liquid crystal (LC) microlens arrays based on controlling the spatial distribution of the Kerr constants of blue phase LC are simulated. Each sub-lens with a parabolic distribution of Kerr constants results in a parabolic phase profile when a homogeneous electric field is applied. We evaluate the phase distribution under different applied voltages, and the focusing prop...
متن کاملA Polarization Independent Microlens using Two Blue-Phase Liquid Crystal Layers with Different Kerr Constant
We propose a new microlens device structure using two polymerstabilized blue phase liquid crystal layers whose Kerr constant is largely different. Such a polarization independent microlens has a simple structure and desired parabolic phase profile. Its applications for 2D/3D switchable displays and other photonic devices are emphasized.
متن کاملExtended Kerr effect of polymer-stabilized blue-phase liquid crystals
Electric-field-induced birefringence of a polymer-stabilized blue-phase liquid crystal BPLC is investigated. In the low field region, conventional Kerr effect holds. As the electric field increases, the induced birefringence gradually saturates and deviates from Kerr effect. An exponential convergence model, called extended Kerr effect, is proposed to fit the experimental data. Good agreement b...
متن کاملPolymer network liquid crystals for tunable microlens arrays
We demonstrate a tunable-focus microlens array using polymer network liquid crystals (PNLCs). PNLCs were prepared by ultraviolet (UV) light exposure through a patterned photomask. The UV-curable monomer in each of the exposed spots forms an inhomogeneous centro-symmetrical polymer network that functions as a lens when a homogeneous electric field is applied to the cell. The focal length of the ...
متن کاملDielectric dispersion on the Kerr constant of blue phase liquid crystals
Dielectric dispersions on the Kerr constant of two polymer-stabilized blue phase liquid crystals (BPLCs) are investigated. An extended Cole-Cole model is proposed to fit the experimental results and good agreement is obtained. As the electric field frequency increases, Kerr constant decreases and the associated dielectric heating effect gradually increases. These results will undoubtedly affect...
