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.
