Abstract
A micro-mirror device includes a substrate and a plate spaced from and oriented substantially parallel to the substrate such that the plate and the substrate define a cavity therebetween. A reflective element is interposed between the substrate and the plate, and a liquid having an index of refraction greater than one is disposed in the cavity between at least the reflective element and the plate. As such, the reflective element is adapted to move between a first position and at least one second position.
