Abstract: The disclosed technology relates to structurant polymers based on polyurethane/polyurea chemistry, which efficiently thicken or gel (i.e., provide structure to) oils and oil mixtures. The disclosed technology further relates to structurant polymers based on polyurethane/polyurea chemistry that are oil soluble or oil dispersible and that provide beneficial properties, such as, for example, desirable clarity and/or feel. In addition, the technology relates to cosmetically and/or household acceptable formulations containing an oil as well as a structurant polymer based on polyurethane/poly-urea chemistry.

Abstract: An optical switch has an array of fibers, an optional lens, and a mirror with two-dimensional tilt adjustment. Light from the array passes through the lens, is reflected by the mirror, and passes again through the lens back towards the array. The input/output fibers are arranged in a two-dimensional pattern designed to avoid undesirable crosstalk between fibers. The pattern may include a plurality of fibers positioned around a central fiber in a circular arrangement. For a 1×8 or 8×1 switch, nine fibers are preferably positioned in a circle around the central fiber, thereby providing geometry that substantially avoids undesirable crosstalk between fibers in the array. In another implementation, the fiber array is implemented using a tapered ferrule housing a central fiber, surrounded by an intermediate layer of six fibers, surrounded by an outer layer of twelve fibers.

Abstract: The invention addresses a micro-electro-mechanical (MEMS) device, or an array of such devices, for use in an optical communication system and a method of manufacture therefore. An embodiment of the device includes a moveable element support structure, a moveable element and torsional members that couple the moveable element support structure and the moveable element and allow the moveable element to gimbal with respect to the support structure. The inventive device includes torsional members that are substantially free of corrosion thereby producing a device with improved response characteristics. The method includes using an etchant that substantially inhibits corrosion of the torsional members.

Abstract: Recognizing the rate-determining nature of the coating removal and recoating steps, applicants have demonstrated that with proper combination of low absorbing polymer, glass and low intensity radiation, UV-induced gratings can be side-written into polymer coated fibers without removing the polymer, thus permitting up the possibility of high speed fabrication of fiber gratings.
