Abstract
Methods and apparatus for modulating light using a tunable light modulation device. The tunable light modulation devices comprises an elastomer structure including at least one elastomer layer, a compliant electrode network of conducting fibers arranged on a first surface of the at least one elastomer layer, a patterned electric conductor arranged on a second surface of the at least one elastomer layer opposite the first surface. The patterned electric conductor includes a plurality of individually-addressable sections, and the compliant electrode network is configured to compress the at least one elastomer layer in the presence of an electric field between the compliant electrode network and one or more of the individually-addressable sections of the patterned electric conductor to produce a voltage-dependent roughening of the at least one elastomer layer.
