摘要： The present disclosure provides optical fiber preforms formed from core canes having large core-clad ratio, intermediate core-cladding assemblies, and methods for making the preforms and core cladding assemblies. The preforms are made with capped core canes. The capping material has a coefficient of thermal expansion less than the coefficient of thermal expansion of the core cane and more closely matched to or lower than the coefficient of thermal expansion of the surrounding cladding monolith in a cane-in-soot process. Presence of the cap reduces stresses that arise from differential thermal expansion of the core cane and cladding materials and leads to preforms having low defect concentration and low probability of failure during subsequent thermal processing steps.

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.

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.
