Abstract
An optical device for modulating the intensity of light from an interferometric reflector. In one embodiment, the optical device can include an optical stack having a reflective layer and a partially reflective, partially transmissive layer for reflecting light. The optical device can also include a fluid cell comprising an absorptive fluid and a transmissive fluid. The optical device can also include a mechanism for controlling the portion of the reflector which is shadowed by the absorptive fluid.
