Device and method for wavelength filtering
First Claim
1. A device for modulating light, the device comprising:
- a movable reflector;
a first partial reflector positioned at a first distance from said movable reflector; and
a second partial reflector positioned at a second fixed distance from said first partial reflector, wherein said movable reflector is movable with respect to said first partial reflector to alter said first distance.

Abstract
Embodiments include devices and methods for wavelength filtering. For example, one embodiment includes a display comprising a plurality of the display elements each comprising a movable reflector, a first partial reflector, and a second partial reflector. The first partial reflector is positioned at a first distance from the movable reflector and forms a first optical resonant cavity therebetween. The second partial reflector is positioned at a second distance from said first partial reflector and forming a second optical resonant cavity therebetween. In various embodiments, the movable reflector is movable with respect to the first partial reflector to alter the first optical cavity. Other embodiments include a method of making devices.
