    摘要: The present invention provides an improved method and apparatus for curing coatings on optical fibers, without creating additional heat and compromising the manufacturing speed of optical fibers. The present invention uses at least one ultrasonic transducer coupled to a component of the optical fiber draw tower, such as the coating die, curing stage device or sheath, to emit ultrasound to the coating of the fiber. The use of ultrasound with current coating cure techniques, such as UV radiation curing, aids in accelerating the coating cure process through the effects of sonolysis, allowing an increase in current manufacturing speeds of optical fibers.

    摘要: A method of fabrication and the resulting structure for a birefringent transmission line having particular application as an optical waveguide. The instant transmission line is fabricated so as to be adapted to maintain the state (e.g. the polarization vector) of polarized electromagnetic radiation propagating therethrough. Birefringence in the instant transmission line is geometrically generated by producing oblong regions having different indices of refraction through a cross-section of the transmission line. A preferred technique by which to generate birefringence includes the method step of bombarding the transmission line with a supply of atomic particules, such as energetic hydrogen ions, whereby to implant a damaged region of oblong cross-section and thereby cause an internal swelling therein. By way of a preferred example, the transmission line herein described may be a single-mode optical fiber.

    摘要: A method of creating optical fiber to exhibit predetermined length-dependent characteristics (e.g., chromatic dispersion, polarization mode dispersion, cutoff wavelength, birefringence) includes the steps of: characterizing the fiber's selected characteristic(s) as a function of length; and performing a “treatment” which modifies the refractive index over the given length to adjust the defined parameter to fall within a defined tolerance window. These steps may be repeated one or more times until the measure of the parameter falls with the defined tolerance limits. The treatment process may include, for example, a low energy actinic radiation exposure, anneal, mechanical strain, DC voltage, plasma application, etc. Indeed, if the treatment process is repeated, a different technique may be used to adjust the refractive index (“different” processes include, for example, modifying the strength/time of a UV exposure, temperatures for annealing, etc.).

    摘要: The present invention provides for an apparatus and method to manufacture optical fiber in a way that produces controlled and patterned diffusion of optical radiation along its length. The novelty of the described invention is that the patterns of diffusion are produced at the time the optical fiber is manufactured. The nullin-linenull manufacturing method avoids the need for post-production treatment of the fiber, which makes the process highly efficient and economical. Light diffusing optical fibers of significant length can be produced. Several manufacturing configurations to achieve the desired effects and their inclusion in the fiber production process are described. The processes can be configured to process optical fibers constructed from a wide variety of known glass, polymeric or other materials. The partially diffusing optical fibers of this invention have applications ranging from illuminated fabrics and toys and to lighting systems and medical instruments. A distributed sensor comprising a light detector coupled to a partially diffusing fiber is also disclosed.
