  • SWITCHABLE GRATING BASED ON ELECTROPHORETIC PARTICLE SYSTEM
    Publication number: 20100134872
    Abstract: A switchable optical component (10) includes a substrate (18) forming a cavity (14). The substrate (18) is configured with a structured surface (24, 26) adjacent to the cavity, and the substrate has a first index of refraction. A fluid (16) contacts the structured surface. Particles (12) are selectively dispersible in the fluid such that a first concentration of particles in the fluid enables the structured surface to provide an optical effect, and a second concentration of particles in the fluid disables the optical effect.
