Fabrication of Polarization-dependent and Polarization-independent Microlens Arrays by Controlling Surface Properties with Electronic Patterning Method

초록

We report the fabrication of a polarization-dependent and independent microlens array (MLA) through the electrohydrodynamic instability of liquid crystal polymer layer with optically anisotropic property. An electrostatic force gradient induced by a patterned electrode produce the anisotropic flow of liquid crystal polymer, as a result, profile of the lens could be made on the transfer substrate. By controlling the surface property of the transfer substrate, we can fabricate optically isotropic and anisotropic MLA.
