    Abstract: A method of manufacturing an optical fiber preform, the method comprising: providing a substantially elongated core preform made out of a core fluorinated glass; providing a substantially elongated and substantially tubular cladding preform made out of a cladding fluorinated glass, the cladding preform defining a bore extending substantially longitudinally therethrough; inserting the core preform into the bore of the cladding preform; fusing the core preform and the cladding preform to each other to produce an intermediate preform; heating the intermediate preform up to a stretching temperature, the stretching temperature being such that the core and cladding fluorinated glasses both have a viscosity of between 10−7 and 10−9 Pa s at the stretching temperature; stretching the intermediate preform at the stretching temperature to produce a stretched intermediate preform; and cutting a section of the stretched intermediate preform. Typically, the stretching temperature is between a vitreous transition temperature and a crystallization temperature of the core and cladding glasses.

    Abstract: Improved photonic band-gap optical fibre The present invention relates in particular to improved photonic band-gap optical fibres that can confine light to a core region of the fibre by the action of both a photonic band-gap cladding and an antiresonant core boundary, at the interface between the core and cladding. According to embodiments of the present invention, a fibre has a core, comprising an elongate region of relatively low refractive index, a photonic bandgap structure arranged to provide a photonic bandgap over a range of wavelengths of light including an operating wavelength of light, the structure, in a transverse cross section of the waveguide, surrounding the core and comprising elongate relatively low refractive index regions interspersed with elongate relatively high refractive index regions and a relatively high refractive index boundary at the interface between the core defect and the photonic bandgap structure, the boundary having a thickness around the core such that the boundary is substantially anti-resonant at the operating wavelength of the fibre. In preferred embodiments, the core boundary is a relatively constant thickness region of glass around a hollow core.
