    Abstract: An embodiment of a double pass modulator includes a reflective polarizer adapted to pass light having a predetermined polarization state therethrough and to reflect substantially all other light, a quarter wave plate positioned to receive and pass light from the reflective polarizer, the quarter wave plate shifting the relative phase of the light passing therethrough by 45° with respect to the optic axis of the plate, and a reflector that receives light from the quarter wave plate and modulates at least a portion of the light incident thereon in a predetermined manner.

    Abstract: A charge control circuit for controlling a micro-electromechanical system (MEMS) device having variable capacitor formed by first conductive plate and a second conductive plate separated by a variable gap distance. The charge control circuit comprises a switch circuit configured to receive a reference voltage having a selected voltage level and configured to respond to an enable signal having a duration at least as long as an electrical time constant constant of the MEMS device, but shorter than a mechanical time constant of the MEMS device, to apply the selected voltage level across the first and second plates for the duration to thereby cause a stored charge having a desired magnitude to accumulate on the variable capacitor, wherein the variable gap distance is a function of the magnitude of the stored charge.

    Abstract: An enhanced Spindt-tip field emitter tip and a method for producing the enhanced Spindt-tip field emitter. A thin-film resistive heating element is positioned below the field emitter tip to allow for resistive heating of the tip in order to sharpen the tip and to remove adsorbed contaminants from the surface of the tip. Metal layers of the enhanced field emission device are separated by relatively thick dielectric bilayers, with the metal layers having increased thickness in the proximity of a cylindrical well in which the field emitter tip is deposited. Dielectric material is pulled back from the cylindrical aperture into which the field emitter tip is deposited in order to decrease buildup of conductive contaminants and the possibility of short circuits between metallic layers.

    Abstract: An electronic device of an embodiment of the invention is for at least partially displaying a pixel of a displayable image. The electronic device includes a first reflector and a second reflector that define an optical cavity therebetween, and which is selective of a visible wavelength at an intensity by optical interference. The electronic device also includes a charge-controlling mechanism to allow optical properties of the optical cavity to be varied by controlling a predetermined amount of charge stored on the first and the second reflectors. The visible wavelength and/or the intensity are thus variably selectable in correspondence with the pixel of the displayable image.
