  • Process and device for growing single crystals, especially of CaF2
    Patent number: 6797058
    Abstract: The present invention relates to a process and a device for growing single crystals, especially of CaF2. Within the framework of said process, a stack of crucibles (100, 101, . . . , 106, . . . ) containing the starting material is successively moved translationally through a melting chamber (C1) and an annealing chamber (C2), said movement being continuous, smooth and without interruption. The present invention provides for the preparation of fluoride, single crystals, particularly optical fluoride single crystals and optical UV &lgr;<248 nm lithography element blanks, most preferably CaF2.

  • Planar optical waveguides with low back reflection pigtailing
    Patent number: 5526452
    Abstract: An optical waveguide component, with a pigtail attached thereto, is disclosed in which a portion of a surface of the component is bevelled and a portion of the endface of the pigtail is bevelled. The bevelled portion of the pigtail endface is oriented to be substantially parallel to the bevelled portion of the component surface or is oriented to be open with respect to the component surface. The pigtail endface can be continuously bevelled to form a substantially conical shape on the pigtail endface, wherein the substantially conical shape is offset from the optical axis of the pigtail.

  • Method of manufacturing and testing integrated optical components
    Patent number: 5447585
    Abstract: A method of manufacturing and testing integrated optical composites in which fiber pigtails are aligned with and attached to the optical output ports of a plurality of integrated optical components on a wafer, prior to separation into individual components. The multiple pigtails are arranged at the ends opposite the wafer, to facilitate optical connections during active alignment and measurement testing.
