    摘要： Cylindrical optical components of quartz glass are known, which have an inner zone made of an inner zone glass, which extends in the direction of the longitudinal axis and is surrounded by a jacket zone made of a jacket zone glass, the average wall thickness thereof varying at least over a part of its length in the direction of the longitudinal axis of the component. The aim of the invention is to provide a method that allows a simple and cost-effective production of such an optical component from quartz glass. A method is proposed according to the invention, comprising the following method steps: (a) providing a first parison made of an inner zone glass, which has a first contact surface on the end face, said contact surface having a conical external contour; (b) providing a second parison from the jacket zone glass; (c) embedding the contact surface with a conical external contour into the jacket zone glass and welding the contact surface to the jacket zone glass, thereby forming a composite parison which has a cone-shaped inner zone area of inner zone glass in a contact area, said inner zone area being surrounded by a jacket zone area having the shape of an inner cone; and (d) elongation of the composite parison to form the optical component or a preproduct of the component.

    摘要： The present invention relates to an optical fiber, wherein PMD will not significantly increase even when an external factor, such as a lateral pressure, a bending and the like, is applied to the optical fiber. The optical fiber is imparted with a twist that is an elastic torsion with stress. In the condition that a twist rate, being the number of rotations per unit length by the twist, is represented by f(z) as a function of a position z in a longitudinal direction of the optical fiber, which has a predetermined twist cycle and is defined such that, in one twist cycle, a twist rotation angle in one direction and a twist rotation angle in the opposite direction are equal to each other, when a proportionality coefficient representing circular birefringence per twist rate is denoted by g, an angular frequency is denoted by ω, and external linear birefringence due to a bending and a lateral pressure is denoted by βe, then an average twist cycle L and an average twist rate γav in the optical fiber satisfy predetermined relational expressions.

    摘要： A multicore optical fibre includes a microstructured cladding material formed from a plurality of cladding elements arranged in an array and each cladding element comprising at least two different materials each having different refractive indices, and a plurality of core elements formed within interstitial regions between adjacent cladding elements. A fibre so formed may have a large number of cores per unit cross-sectional area as compared with prior art fibres, and thus allows the fibre to have relatively short distances between adjacent cores for a given required inter-core isolation. A fibre so formed has utility in many areas requiring high core density, such as inter-chip optical communication, or optical communication between circuit boards.
