摘要： Disclosed are methods for reducing polarization mode dispersion (PMD) in single mode fiber by spinning the fiber during the drawing process in accordance with a spin function having sufficient harmonic content to achieve low levels of PMD for commercial fibers for which the beat lengths of the fibers, including the beat lengths of different portions of the fibers, are available and thus not readily known in advance. The spin functions disclosed take advantage of certain resonances in energy transfer between polarization modes to achieve substantial reductions in PMD for a wide range of beat lengths. Examples of suitable spin functions include frequency-modulated and amplitude-modulated sine waves.

摘要： A method of manufacturing an optical fiber, whereby a fiber (7) is drawn from a molten extremity (3) of a preform (1) and is subsequently subjected to a torque, thereby causing a portion of the fiber to be twisted about its longitudinal axis and to be endowed with a spin, whereby the torque is applied by running the fiber (7) between a pair of wheels (11a, 11b) which rotate in mutually opposite senses about two different rotational axes (13a, 13b), each wheel (11a, 11b) having a peripheral curved surface (15a, 15b), the wheels (11a, 11b) being thus arranged that the fiber (7) runs substantially tangential to their curved surfaces (15a, 15b) and is pressed therebetween, the wheels (11a, 11b) being moved back and forth relative to one another in a direction (d, d') substantially perpendicular to the fiber (7) so as to cause the fiber (7) to be rolled back and forth between their curved surfaces (15a, 15b).

摘要： A single mode optical waveguide having reduced polarization mode dispersion and a method for making such a waveguide is disclosed. Perturbations are introduced into the waveguide core to couple power between the two polarization modes. A model calculation shows that the perturbation length may be of the order of the correlation length. The inventive waveguide is robust in that polarization mode dispersion is reduced even if perturbations are impressed on the fiber after manufacture.

摘要： Optical waveguide cores having refractive index profiles that vary angularly about a propagation axis of the core can provide single-mode operation with larger core diameters than conventional waveguides. An optical waveguide includes a core that extends along a propagation axis and has a refractive index profile that varies angularly about the propagation axis. The optical waveguide also includes a cladding disposed about the core and extending along the propagation axis. The refractive index profile of the core varies angularly along a length of the propagation axis.
