Abstract
An optical switch includes a first fluid, and a second fluid positioned adjacent to and in contact with the first fluid. The interface between the first fluid and the second fluid defines a reflective surface. The optical switch also includes electrodes for applying an electrical field across the second fluid to alter the geometry of the reflective surface and redirect an incident light beam in one or more directions.
