    Abstract: Consistent with the present disclosure, a package is provided in which the PLC substrate, for example, is bonded to the underyling carrier though a limited contact area. The rest of the substrate is detached from the carrier so that stresses are applied to a limited portion of the PLC substrate. The PLC itself, however, is provided over that portion of the substrate that is detached from the carrier, and thus experiences reduced stress. Accordingly, high modulus adhesives, as well as solders, may be used to bond the PLC substrate to the carrier, thereby resulting in a more robust mechanical structure.

  • Patent number: 6442322
    Abstract: This invention relates to an optical fiber management device that allows optical fiber to be placed in very restricted areas such as small modules. This device also provides an embedded conduit system that prevents the optical fibers from over bending and inhibits optical transmission. Moreover, the device of the present invention allows free movement of the optical fibers therethrough, if necessary. The result is a flexible and useful way to manage the location of the optical fibers and facilitate the connection of optical adapters.

  • Patent number: 6079881
    Abstract: An receptacle is provided for receiving a fiber optic connector along an optic axis. The receptacle includes a housing having an open end for receiving the fiber optic connector. A pair of shutter members are pivotally mounted on the housing at opposite sides of the open end of the housing for pivotal movement toward and away from each other to close and open the open end. The shutter members extend across the optic axis when the shutter members are closed, The shutter members are pivotable away from the optic axis upon engagement by the inserted fiber optic connector. The shutter members have inner ends which are overlapped when the shutter members are closed to ensure against light leakage along the optic axis. The fiber optic connector has a mating end which is transversely offset for engaging one of the shutter members before the other shutter member upon insertion of the connector into the open end of the receptacle.

  • Patent number: 5907650
    Abstract: An optical fiber array connector in which the tolerance of the diameter of the mask openings are not factors in the overall positioning of the plurality of fibers. The array includes a mask element with rear and forward surfaces and a plurality of openings that communicate through these surfaces. A plurality of optical fibers include fiber ends having substantially truncated conical side surfaces that extend through the openings and engage the portions of the mask openings nearest the mask rear surface. A method includes preparing the fibers to form a conical surface at their distal ends, preparing the openings in the primary mask each with a diameter less than the diameter of the fiber cladding or second layer, inserting the conical fiber ends until the conical surfaces engage the mask opening walls, applying bonding material to the mask forward surface and exposed tips, grinding and polishing the exposed tips and bonding material surface to truncate the cones and expose the fiber core diameters.

  • Patent number: 5790731
    Abstract: The invention includes an interconnection assembly for coupling optical fibers to respective optical waveguides of an optical integrated circuit (OIC). The interconnection assembly includes an OIC assembly preferably formed by adhering a protective plate to a substrate on which the OIC and its optical waveguides are integrated. In one end of the OIC assembly, ends of the optical waveguides are exposed. Importantly, the protective plate and the substrate have substantially similar thermal coefficients of expansion to reduce or eliminate stresses or strains on the adhesive when the interconnection assembly is subjected to temperature and/or humidity conditions that are different from those under which the interconnection assembly was formed. The interconnection assembly also includes an optical fiber array that houses end portions of the optical fibers.
