Abstract:
An apparatus for modulating light includes a first electrode, a second electrode, and a sealed enclosure. The first electrode includes a frequency selective surface operable to reflect light having a first wavelength, and the second electrode is spaced apart from the first electrode. The sealed enclosure stores electrophoretic fluid and at least a portion of the sealed enclosure is positioned between the first electrode and the second electrode. A plurality of particles are suspended in the electrophoretic fluid. The particles are capable of absorbing light having the first wavelength. In addition, the first electrode is capable of attracting the particles towards the frequency selective surface when an electrical bias is applied between the first electrode and the second electrode.
