  • Patent number: 10370280
    Abstract: A method of making an optical fiber with multiple openings comprising the steps of fabricating an extrusion die using additive manufacturing such that the extrusion die has a plurality of channels that combine inside the die into another set of channels, extruding a glass, forming a fiber optic preform having a plurality of longitudinal openings that run the entire length, attaching a barrier layer for pressure application, and stretching the preform into an optical fiber with multiple openings. An extrusion die comprising an additive manufactured material, having a proximal side having openings and having a distal side having openings, wherein the openings of the proximal side are of feed channels, wherein the openings of the distal side are of forming channels, and wherein in side the body of the die, two of the feed channels combine the forming channels.

  • Patent number: 10359574
    Abstract: Systems and methods are provided for mechanically encapsulating an infrared transmitting optical fiber, removing any power coupled to the cladding of the infrared optical fiber, and bridging the thermal properties between the optical fiber and the mechanical ferrule used. Embodiments of the present disclosure have several advantages over prior systems. For example, in an embodiment, the transmitting ferrule does not require epoxy to mount the fiber to the ferrule, isolates the front face of the fiber, and allows for high power to be incident on the connector without damage by reducing the thermal induced stress and managing any stray light coupled to the core.

  • Patent number: 10338315
    Abstract: Systems and methods are disclosed for splicing crystal fibers to silica glass fibers. Embodiments of the present disclosure provide mechanically stable bonds with negligible optical transmission loss by splicing fibers through a thermally enhanced reaction bonding process at lower temperatures than the melting point of the crystal. In an embodiment, mixing of the materials at elevated temperatures forms a stable intermediary material which enhances strength and reduces the transmission losses.

  • Patent number: 4924303
    Abstract: A TV still frame image, perhaps with an accompanying audio segment, information retrieval system is disclosed. The system allows end users to search for, order, and retrieve still frame video images, which images are then displayed on a conventional television set. Related audio sound can be heard over the same television set, over a telephone, or over another audio device. A data base of images and sound is stored on storage devices that are controlled by a general purpose computer system. This data base is located at the "head end" of the system. In one mode of operation, an end user requests and receives a particular video image(s), and perhaps a sound segment(s), from a plurality of such images that are continuously being sent to all end users. In a second mode of operation an end user requests a data base image that is not presently being sent to all end users.
