Abstract
A liquid crystal is configured as a photonic crystal by an establishment of a network of biased liquid crystal regions within the liquid crystal. The liquid crystal is situated between a dielectric plane including an electrode plate and a glass plate, and a dielectric plane including a glass plate and a plurality of electrode pixels. The network is established by a selective application of one or more electric potentials between an electrode plate and one or more of the electrode pixels.
