Dual-Focusing Microlens Arrays Based on Electrohydrodynamic Pattering Method

초록

We proposed a dual-focusing microlens arrays (MLAs) based on the electrohydrodynamic (EHD) patterning method using a liquid crystalline polymer (LCP). The key mechanism of the EHD patterning method is an anisotropic flow of the LCP film induced by a fringe-field effect. By this method, we can fabricate a MLA having a polarization-dependence without complicated process. Therefore, it is suitable for a double-layer optical storage disc and other optical devices.
