Abstract: An optical micro-electro-mechanical system (MEMS) switch is disclosed. In a preferred embodiment the optical MEMS switch is used as an M x N optical signal switching system. The optical MEMS switch comprises a plurality of optical waveguides formed on a shuttle for switching optical states wherein the state of the optical switch is changed by a system of drive and latch actuators. The optical MEMS switch utilizes a latching mechanism in association with a thermal drive actuator for aligning the waveguide shuttle . In use the optical MEMS switch may be integrated with other optical components to form planar light circuits (PLCs). When switches and PLCs are integrated together on a silicon chip, compact higher functionality devices, such as Reconfigurable Optical Add-Drop Multiplexers (ROADMs), may be fabricated.

Abstract: A silicon demultiplexer, a plurality of silicon switches and a silicon multiplexer are monolithically integrated on a single silicon chip. In embodiments, the silicon demultiplexer and the silicon multiplexer each comprise a diffraction grating. In other embodiments, the silicon demultiplexer and the silicon multiplexer each comprise an arrayed waveguide grating. In various exemplary embodiments, the silicon optical switches comprise optical switches, micromachined torsion mirrors, electrostatic micromirrors, and/or tilting micromirrors. In use, an optical signal comprising a multiplexed data stream is input into the monolithic reconfigurable optical multiplexer. An optical signal that comprises a modified multiplexed data stream may be output. In an optical communications system, the silicon demultiplexer communicates with an input optical fiber, the plurality of silicon optical switches communicate between the silicon demultiplexer and the silicon multiplexer, and the silicon multiplexer communicates with an output optical fiber. In various embodiments, the optical switches are fabricated to be self-aligned.

Abstract: This disclosure provides an aperture plate coated with a composition comprising a fluorinated compound and an organic compound selected from the group consisting of a urea, an isocyanate and a melamine. This disclosure also provides a process of applying a coating composition to an aperture plate, comprising adding a fluorinated compound, an organic compound selected from the group consisting of a urea, an isocyanate and a melamine, and an optional catalyst together in a solvent to form a coating composition, applying the coating composition to a base film, and curing the base film. This disclosure also describes replacing the aperture plate with polyimide film, where the polyimide film is coated with the above-described coating composition before a laser cutting process.

Abstract: Methods form a multi-color electrophoretic display. The methods include providing microcapsules, wherein the microcapsules have an electrostatic charge, and wherein the microcapsules comprise, a shell that is transparent and a display medium within the shell, wherein the display medium is comprised of either (a) at least two sets of differently colored particles in a substantially clear fluid, or (b) at least one set of colored particles in a differently colored fluid. The methods include transferring the microcapsules to a substrate, wherein the electrostatic charge of the microcapsules attracts the microcapsules to the substrate, wherein a display layer of microcapsules is formed on the substrate. The methods include positioning a conductive substrate adjacent to the substrate, wherein the substrate is located between the display layer and the conductive substrate. In use, the conductive substrate applies an electric field to the display layer, and wherein the sets of particles within each microcapsule in the display layer are movable within the microcapsule by the electric field.
