Abstract:
1. A light modulating device comprising: a first substrate substantially transparent to light; a second substrate substantially transparent to light, the second substrate substantially parallel to the first substrate and spaced from the first substrate; at least one support stack coupling the first substrate and the second substrate together; a first partially reflective layer coupled to the first substrate; a second partially reflective layer coupled to the second substrate, the second partially reflective layer substantially parallel to the first partially reflective layer and spaced from the first partially reflective layer, the first partially reflective layer and the second partially reflective layer defining a cavity therebetween; at least one movable layer supported by the at least one support stack, the at least one movable layer movable within the cavity along a direction generally perpendicular to the first and second partially reflective layers; and a first reflective surface and a second reflective surface coupled to the at least one movable layer to move within the cavity with the at least one movable layer, the first reflective surface and the first partially reflective layer defining a first sub-cavity therebetween, the second reflective surface and the second partially reflective layer defining a second sub-cavity therebetween.
