Polarization independent static microlens array in the homeotropic liquid crystal configuration
We propose a novel microlens array structure in a homeotropic liquid crystal (W) configuration. The symmetry of molecular ordering in the homeotropic alignment on a circular surface relief structure provides the polarization independent focusing characteristics of the LC microlens. The surface relief structure of polydimethylsiloxane (PDMS) supports an initial convex lens driving scheme of the LC microlens as well as easy modification with great aging property.
