  • Publication number: 20070133928
    Abstract: A canted-fiber duplex optical subassembly is disclosed herein. The optical subassembly transmits and receives optical signals by way of a single optical fiber, which has a canted surface on one end. A light source sends transmission optical signals, which are refracted through the canted surface and then enter the optical fiber. Reception optical signals in the optical fiber are reflected by the canted surface and are then received by an optical detector.

  • Patent number: 6900136
    Abstract: A method for reducing RIE lag (reaction ion etching lag) in a deep silicon etching process forming trench openings is described. The method can be carried out by either a photolithographic means wherein trench openings of the same planar area are patterned on the silicon substrate, or by a pressure means in which the chamber pressure during the reactive ion etching process is increased to reduce or eliminate the RIE lag effect. By increasing the chamber pressure at least 50% from that normally incurred in a reactive ion etching process, and preferably at least 100%, the RIE lag effect can be completely eliminated resulting in an inversed RIE lag in which a larger etch depth is achieved for the trench openings that have the smallest width.
