Abstract: An optical echelle grating for use with a switching fabric to provide different wavelength switching assemblies such as an optical cross connect. The single grating receives a plurality of multiplexed input optical signals and provides optical signals corresponding to the individual wavelength channels to a switching fabric. The switching fabric routes the signals corresponding to the wavelength channels appropriately and the signals then propagate to the grating once more and are wavelength multiplexed.

Abstract: An electrostatic comb drive suitable for micro-electro-mechanical systems (“MEMS”) application uses shaped fingers to achieve bi-directional actuation from a unipolar actuation pulse. The finger shape also provides auto-braking of the movable member of the drive using a simple actuating pulse. In a further embodiment, an end stop inhibits overshoot and a back spring pushes the movable portion of the device back toward an operating position. In yet a further embodiment, a Vernier scale is provided on the movable portion of the drive relative to the fixed portion of the drive to indicate relative shift of these portions after the device is fabricated.

Abstract: The present invention involves in situ laser patterning of thin-film layers during sequential deposition of the different layers. The layers may be applied using any known method of film deposition. The method of the present invention involves laser ablation to remove unwanted portions of the coating layers, including color filter materials, that have been sequentially deposited onto substantially the entire surface of a substrate. By controlling the depth of the laser ablation removal of the deposited films, it is possible to remove any portion of a film or layers of films or coatings that have been sequentially coated onto the surface of the substrate and to thereby control the depth and location of color filter materials coated upon the substrate. This patterning process can be employed in conjunction with any film deposition technique known in the art, including vacuum, wet chemical or dry processing deposition techniques, but is preferred with vacuum deposition.
