Abstract
Methods and apparatus for modulating light thorough a transparent laminate structure. The transparent laminate structure includes at least one soft dielectric layer and at least one stiff dielectric layer having a stiffness greater than the stiffness of the at least one soft dielectric layer. The transparent laminate structure further comprises a plurality of stiff conductive elements formed on a surface of the at least one soft dielectric layer that, in the presence of an electric field, compress the at least one soft dielectric layer to alter a morphology of the surface of the at least one soft dielectric layer on which the plurality of stiff conductive elements are formed. Light incident on the surface of the at least one soft dielectric layer is scattered by the undulating morphology of the surface, thereby reducing the transmission of light through the transparent laminate structure.
