    摘要: An optical fiber having a carbonized or diamond-like coating and a method for manufacturing same is provided. The carbonized or diamond-like coating is formed by modifying the polymer coatings typically used by optical fiber manufacturers to protect the optical fiber from mechanical and environmental damage. The carbonized coating is formed by heating the fiber at a controlled temperature for a predetermined period of time to carbonize the polymer layers. This carbonization results in a reduced fiber diameter resulting in excellent adhesion of the carbonized or diamond-like coating without substantially decreasing the mechanical strength of the optical fiber. The carbonized coating also assists in mounting the optical fiber, especially where adhesion of the coating to the cladding of the fiber is important, such as in a device where strain is applied to a fiber grating to tune the photosensitivity of the grating.

    摘要: A method is disclosed for securing an optical fiber to a packaging substrate with a bismuth-containing alloy of solder. For this purpose, the substrate may be provided with metallic pads or a blanket metallization to which the alloy or solder can adhere and the optical fiber is then positioned above such substrate and bonded to it with the alloy or solder. Also, a cavity or recess may be formed in the substrate in which the optical fiber is positioned and into which the alloy or solder is delivered in preformed or liquid state and is solidified in the cavity or recess while bonding the fiber. An optical assembly is also disclosed in which at least one optical fiber is bonded to the substrate by means of the bismuth-containing alloy or solder.

    摘要: A device for applying light conductive fibers onto substrates and having a mounting yoke, a holding device and a stamping device. The holding device is configured as a U-shaped base body with an upward arching outside area having guide grooves and holders for installing the fibers in the device. The stamping device consists of a stamp, a stamp neck and a stamp head, which are inserted and linearly guided in the U-shaped die sink in the holding device. The device ensures a precise positioning of fibers and in particular of functional units in fiber segments. Fiber breaks can be nearly ruled out with the application method. The separating foils ensure that the device can be removed after the adhesive has hardened, so that no force is exerted onto the fiber through excess adhesive that sticks.

    摘要: A fiber optic package is provided in which substantially zero strain is exerted on a portion of an optical fiber containing a Bragg grating. The package includes a fastener securing a first portion of the optical fiber and a mandrel, for example, around which a second portion of the fiber is looped. The Bragg grating is preferably located between the first and second portions of the optical fiber. As a result, the portion of the optical fiber containing the Bragg grating is isolated from stresses originating in parts of the optical fiber beyond the mandrel and the fastener. The portion of the optical fiber containing the Bragg grating, therefore, remains substantially stress-free.

    摘要: A lightweight stacked optical waveguide using two plastic substrates having nano-structure gratings and a single glass substrate sandwiched between them. The nano-structure gratings face each other, and are each encapsulated within the optical waveguide. The two plastic substrates are each adhesively secured to the central glass substrate rather than to each other to provide sufficient securing strength and precisely establish and maintain an air gap between the substrates. The thickness of the plastic substrates and the glass substrate are selected such that the stacked optical waveguide is lightweight, but also has sufficient drop performance. The stacked optical waveguide can be efficiently manufactured as the adhesive bonds a plastic substrate to a glass substrate.

    摘要: A fabrication method of the multi-core fiber Bragg grating (FBG) probe for measuring structures of a micro part based on the capillary self-assembly technique, wherein the diameter of the fiber (6) inscribed with FBG is reduced using a mechanical method or an etch method by the hydrofluoric acid; the fibers (6) inscribed with FBG, whose diameter has been reduced, are inserted into a tube (7) through its terminal with an inner taper angle; the FBG terminals of these fibers (6) are immersed into the UV adhesive (10) of a low viscosity and the UV adhesive (10) is raised in the gaps between the fibers (6); or the UV adhesive is dropped on the these fibers (6) and the capillary bridge between the fibers (6) is formed; a most compact structure of the fiber bundle is formed as a result of the capillary self-assembly; the fiber bundle is cured using a UV light and the multi-core FBG (11) is therefore formed; the terminal of the multi-core FBG (11) is polished with an optic fiber polishing machine and then a spherical tip is fabricated with the melting fiber method or the installation method of a micro ball; therefore, a multi-core FBG (11) probe can be achieved. The method features low crosstalk between signal of FBG, inexpensive and low insertion loss.
