1. An optical device, comprising:
a first set of one or more electrodes;
a second set of one or more electrodes distinct and separate from the first set of one or more electrodes; and
a medium that includes liquid crystal physical gel, wherein the medium is located between the first set of one or more electrodes and the second set of one or more electrodes and the liquid crystal physical gel includes liquid crystals and a gelator selected from a group consisting of: cholesteryl stearate, a combination of a fatty acid and mesogen monomer, or a side-chain liquid crystalline polymer.
