摘要： Method and apparatus for producing metal-coated optical fiber involves feeding a length of glass fiber through a first solution bath so as to plate a first predetermined metal on the glass fiber via electroless deposition. The length of glass fiber is passed continuously from the first solution bath to a second solution bath adapted to plate thereon a second predetermined metal via electrolytic plating such that the optical fiber contacts an electrode only after at least some of the second predetermined metal has been applied. The length of glass fiber may be passed continuously from the second solution bath to a third solution bath adapted to plate thereon a third predetermined metal via electrolytic plating.

摘要： A coating is applied on a first end face of an optical component which includes a cladding and a core for guiding light. The first end face has a cladding front face and a core front face. The core front face is covered with a mask, the coating is applied onto the first end face, the coating s removed from the masked core front face, and for covering the core front face, a lacquer layer made of a photo resist is applied onto the first end face. The photo resist is exposed to light from the rear side only in the region of one of the front faces such that light is input on the second end face of the component only in one of the two regions, and the lacquer layer is subsequently selectively removed.

摘要： Embodiments of the present disclosure relate to a system and method to detect hydrogen leakage. The system uses a fluid sensing apparatus (104), a light source (120) and a photo detector (122). The nano-crystallized palladium gratings (118) are used as sensors which expand sensitively upon exposure to the hydrogen (H2). In an embodiment, the hydrogen sensing is based on monitoring the changes in the diffraction efficiency (DE) which is defined as the ratio of the first and the zeroth order diffracted beam intensities. The diffraction efficiency undergoes large and sudden changes as the nano-crystalline Pd grating becomes highly disordered due to PdHx formation. An embodiment of the present disclosure also relates to producing nanocrystalline Pd diffraction gratings along with the design and fabrication aspects of an indigenously built optical diffraction cell for H2 sensing.

摘要： An optical corrosion sensor employs an optical fiber Bragg grating 20 embedded within an optical fiber 18. The grating 20 has a coating 40 made of a material, such as aluminum, which corrodes or can otherwise be removed. The coating 40 exerts forces 46 radially inward around and along the grating 20 so as to cause the wavelength bandwidth of the grating reflectivity profile to become broader and to be shifted relative to its uncoated condition. Also, the forces on the grating 20 are reduced when the coating corrodes, thereby causing the wavelength bandwidth and shift of the reflectivity profile of the grating to narrow and to return to its uncoated condition.

摘要： A method for forming two conductive films isolated electrically from each other on the surface of a fiber is provided. According to the method, a fiber is attached into the grooves on a silicon substrate using photoresist as glue. A photoresist pattern for a conductive film on the surface of the fiber is formed by a photolithography process. After wet-etching some amount of the fiber on the patterned area, which is needed for lifting off a metal film deposited on the unnecessary area, a metal film is deposited over whole area of the wafer. Removing photo-resist by a heated stripper solution leaves a metal film only on the patterned area of the fiber and detaches the fibers from the grooves of the wafer The second metal film on the other side of the fiber can be formed by the same procedures as the first metal film except that the deposited surface of the fiber must be attached to the grooves upside down. The poled fiber using two conductive films can be applied to manufacture elements used in opto-electronic and fiber communication devices such as a modulator, a tunable filter and a switch, an electric field sensor, and a nonlinear fiber optics device such as a frequency converter, a dispersion compensator.

Preferably the insulating frame comprises a resin selected from the group consisting of acrylic resins, polyvinyl chloride resins and polycarbonate resins.

Adjacent to the metal filament a first conductive plate is attached to the insulating frame at a first distance from the metal filament. A second conductive plate attaches to the insulating frame at a second distance from the metal filament. The first plate and the second plate are adapted for connection to the positive pole of a source of electrical energy. The nonconductor is at least one optical fiber having a conducting portion in contact with the metal filament to provide connection of the conducting portion to a negative pole of the source of electrical energy. In one embodiment of an assembly according to the present invention, there is a plurality of optical fibers each having a conducting portion in contact with the metal filament. An electrode assembly may be used in a process according to the present invention to provide a conductive composite coating on the surface of a nonconductor, preferably an optical fiber.

摘要： Method and apparatus for producing metal-coated optical fiber involves providing a length of optical fiber having a glass fiber with or without a carbon layer surrounded by a liquid-soluble polymeric coating. The optical fiber is passed through a series of solution baths such that the fiber will contact the solution in each bath for a predetermined dwell time, the series of solution baths effecting removal of the polymer coating and subsequent electroless plating of metal on the glass fiber. The optical fiber is collected after metal plating so that a selected quantity of the metal-coated optical fiber is gathered, Preferably, the glass fiber passes through the series of solution baths without contacting anything except for the respective solution in each.
