ABSTRACT:
A transparent electrode has a grating formed thereon, the dimensions of the grating selected to prevent light transmission at a given wavelength or range of wavelengths. A non-wetting transparent liquid covering the grating is held in place by a second electrode. Application of an electrical field between the electrodes causes the liquid to be drawn into the space between the grating ridges, allowing light transmission.
