    Abstract: A method for making a highly birefringent optical fiber includes providing a preform with a substantially circular cross-section. The preform (110) includes a core region (120, 140) having a substantially circular cross-section and a substantially elliptical cladding region (134) adjacent the core region. The outer surface of the preform (130) is modified to create a shaped preform (150) with a non-circular cross-section. The shaped preform (150) is then drawn at a temperature and draw rate sufficient to provide an optical fiber (160) with the non-circular cross-section of the shaped preform. Also disclosed is a highly birefringent optical fiber (160) having a substantially circular core region (170), a surrounding substantially elliptical cladding region (164) and a non-circular outer geometry, such as planar surfaces (163, 165). A method of connection such optical fibers having outer planar surfaces using a specially adapted jig (280) is also disclosed.

    Abstract: An improved polarization preserving birefringent fiber optic member is provided having cross-sectional circular cladding and core members of soft glasses. A metallic coating of an approximately circular configuration, that is offset from the axis of the core and cladding members, is provided with sufficient thickness to provide an anisotropic variation in compressional strain on the core member to create the anisotropy of the refracted index of the core member for preserving polarization characteristics. The optical fiber can be formed by heating a mechanical composite of a core rod and cladding tube, drawing the core and cladding to form a fused fiber and transporting the drawn fiber through a coating bath to provide the variation in thickness.

    Abstract: Method for manufacturing optical fibers, comprising: cutting mirror-symmetrical grooves (2, 3) on a preform rod (1 ) which is inserted into a tube (4) of optical material; fusing the preform rod and the tube in a nonworking area; pulling the fused preform rod and tube into a preform which has longitudinal channels defined by the grooves (2, 3) and the tube (4); cutting the preform (5) into segments; etching the longitudinal channels; sealing segment end(s); assembling segments with a capillary tube and tubular process holder; joining the segment and capillary tube on a side opposite to the tubular process holder; drawing the preform segment into an optical fiber, and applying a protective strengthening coating on the drawn optical fiber. As a result, an optical fiber is produced, which has birefringent properties influenced by dimensions of the mirror- symmetrical grooves and the etching step.

    Abstract: A hollow core fiber has a cladding comprising a matrix of cells, wherein each cell comprises a hole and a wall surrounding the hole. The fiber further has a hollow core region comprising a core gap in the matrix of cells, wherein the core gap spans a plurality of cells and has a boundary defined by the interface of the core gap. The matrix of cells comprises a plurality of lattice cells, and a plurality of defect cells characterized by at least one difference in at least one property from that of the lattice cells. The cells at the core region boundary include lattice cells and defect cells that are arranged in a pattern that define two orthogonal axes of reflection symmetry, so as to produce birefringence in a light propagating through the hollow core fiber.
