    摘要: A splice for holding the ends of optical fibers in end to end relationship includes a pair of sections having mating planar surfaces in engagement. One of the surfaces has an axially aligned groove facing the other surface to form an opening. The fiber receiving member comprises an elastomeric material of sufficient resilience to permit the opening to expandably receive optical fibers dimensioned larger than the opening. A sleeve is mounted about the receiving member for holding the sections in assembled relationship.

    摘要: A holographic video disc system is described in which the baseband information for successive horizontal television line intervals is recorded as successive holograms of one-dimensional line images in a spiral track on the surface of a disc of material. A spiral guiding track is also formed in the surface of the disc immediately adjacent to the spiral track of holograms. The recording system includes a laser beam which is modulated with the baseband video information. The beam is divided into a reference beam and a data beam. A beam deflector scans the data beam through a chosen angle at the horizontal television sweep rate, while the reference beam is unaffected. The reference beam and data beam are intersected at the surface of a record medium and form a surface relief hologram on that surface. Since the data beam is being scanned at the horizontal sweep rate, one-dimensional line images, each of which contains the baseband video information for one horizontal television line interval, are holographically recorded. The record medium is rotated relative to the data beam and reference beam so that a spiral track containing a plurality of the holograms of one-dimensional line images is formed in the surface. During a playback, the location of the spiral guiding track is sensed and one of the hologram forming beams is duplicated thereby reconstructing the other. The reconstructed beam is detected and the baseband video information removed therefrom for application to a standard television receiver.

    摘要: Interferometric multimode fiber optic switches and modulators include combinations of various components. Two electro-optical crystals have a dielectric beam splitting coating affixed to portions thereof. The coated portions of the two crystals are juxtaposed. Means are provided for varying indices of refraction of the two crystals with respect to each other. Light entering into the first crystal and traveling within the two crystals can be switched to selectively exit from one crystal or from the other by varying the index of refraction of one of the crystals with respect to that of the other. By interferometric principle of operation, the phase relation of light is transformed into spatial direction. The crystals can be selected from the group consisting of lithium niobate, lithium tantalate, and barium strontium niobate. The dielectric beam splitting coating can be formed of multiple layers of material such as zirconium oxide and silicon dioxide. The indices of refraction of the crystals are varied by applying electric fields of one polarity at opposite surfaces thereof. Light enters the various crystals, and is reflected, and is transmitted at various surfaces thereof so that, upon entering a particular area within the crystals, reinforcement or interference of light can occur.

    摘要: A telecentric optical fiber connector, wherein light from an optical fiber is emitted from the connector lens in a comparatively large diameter parallel beam, includes two primary components: an integral optical quality plastic connector body having an annular planar reference surface substantially perpendicular to an optical axis. A convex lens surface is molded, recessed inward from the reference surface. The body is substantially cylindrical, with exterior means thereabout so that it can be engaged with a similar body. The opposite axial end of the body has a central cylindrical cavity therein which extends to a point which is one focal length from the lens surface. A fiber holder, which holds an optical fiber centrally within an axial hole, abuts an end of the fiber against the point one focal length from the lens surface, and can be engaged with index-matching material.

    摘要: A method for coupling light from one or more light-emitting devices into corresponding optical fibers includes placing the light-emitting devices on the top surface of a substrate and forming, by photolithographical means, on the top surface of said substrate V-grooves for holding fibers in precise relationship with said light-emitting devices. Additionally, alignment pedestals or posts are formed on said substrate in predetermined relationship to the light emitting devices and alignment V-grooves are photolithographically formed on the top surface of said substrate parallel to said fiber V-grooves. The substrate is cleaved into two sections and said sections are assembled in orthogonal relationship with the section containing the light-emitting devices and alignment posts section being secured to the section containing the fiber and alignment V-grooves so that said posts fit into said alignment V-grooves, thereby aligning the fiber V-grooves with the light-emitting devices.

    摘要: A one-piece molded elastomer splicer for permanent or temporary coupling of guided light between two optical fibers. Two cleaved fibers to be spliced are inserted into opposite ends of an elastic capillary tube somewhat smaller in diameter than the fibers, and pushed in until they meet in the center. Symmetrical elastic restoring forces automatically align the two fiber axes along the axis of the tube. When desired, the splicer can be transparent so that the resulting splice quality can be checked with a low-power microscope. Manual insertion of the fibers is possible with care, but a simple mechanical insertion jig is suggested. An optical fiber connector with built-in fiber-to-connector splice means connects two optical fibers with very low insertion losses even after many connect/disconnect cycles, with a simple and reliable means for installation in the field. The connector has a central mating interface, fabricated, aligned, polished, and anti-reflection coated at the factory, but with a built-in splicer for attaching to fibers in the field by the user.

    摘要: Optical fibers are held and aligned by means of a base member and a cover. The base member has a longitudinal recessed V-shaped groove along a fiber engaging face thereof, and a plurality of rectangular transverse slots spaced along the groove. The slots extend to a depth extending the groove. The cover has a longitudinal extended V-shaped protuberance along a face of the cover which engages the base member. The protuberance corresponds in size and shape to the recessed V-shaped groove, but is blunt at its apex. A plurality of rectangular transverse inverted V-shaped fingers are spaced along the protuberance, and are blunt at their apices. The fingers have a length not exceeding the depth of the slots.A system for splicing two optical fibers in alignment with each other utilizes three of the foregoing clamps, two to hold the fibers temporarily in place and one as the splice part itself. Optical adhesive is used for affixing the ends of the fibers and the splice clamp to each other.

    摘要: A holographic digital data processing system is described in which the data is stored holographically in a recording medium with the data insertable and retrievable in a sequential manner. A modulated data beam and a similarly modulated reference beam are passed through various deflectors to intersect at the recording medium to form the local holographic pattern. The location in the recording of the intersection is controlled by a page deflector which deflects both beams through the same angle and the angle of intersection is controlled by a data deflector which deflects only the data beam. Therefore, each data bit is recorded with a distinct angular relationship between the interfering data and reference beams. During reconstruction, the reference beam is occluded and the data beam is passed through both the data deflector and the page deflector to intersect the recording medium at the unique address of a single bit of digital data which is desired to be read out. The image of that bit is formed in an image plane at a fixed location for all bits. A single photodetector is positioned at that location and serves to read-out the data stored in the holographic memory. In this manner, sequential digital data storage and retrieval is accomplished with a holographic storage medium.

    摘要: A quasi-achromatic configuration of two nonreciprocal optical rotators coupled by linear retardation elements based on total internal Fresnel reflection, such that wavelength or temperature effects on the optical rotator elements compensate one another to give quasi-achromatic isolation and/or temperature stability when this optical configuration is incorporated into an optical isolator or circulator. A quasi-achromatic optical isolator through which a light beam within a wavelength range about a nominal wavelength may propagate is made from a sequence of elements having a first plane polarizer accepting said light beam as an input, said light beam then passing through in sequence, a first Faraday rotator, a first wavelength independent linear retardation element, a second Faraday rotator, a second wavelength independent linear retardation element, and said light beam exiting said isolator undiminished in intensity through a second plane polarizer. A quasi-achromatic optical circulator having first, second, third and fourth ports is provided such that said circulator may accept a light beam within a wavelength range about a nominal wavelength and direct it to a succeeding port. A light beam enters said circulator through a first polarizing beam splitter adjacent to said first and third ports and passes through sequentially a first Faraday rotator, a first wavelength independent linear retardation element, a second Faraday rotator, a second wavelength independent linear retardation element and a second polarizing beam splitter adjacent to said second and fourth ports of said circulator, whereby said light beam is transmitted undiminished in intensity to the next succeeding port.
