    Abstract: PURPOSE:To obtain easily a single-mode optical fluoride fiber having a core of a small diameter by putting a fluoride glass preform having a core-clad structure in a fluoride glass pipe and by heating and drawing them. CONSTITUTION:A fluoride glass preform 8 having a core-clad structure is prepd., and it is heated, drawn, and put in a jacket pipe 9 covered with a fluororesin tube 10. While evacuating the pipe 9 with a rotary pump, the preform 8 and the pipe 9 are heated with a small-sized electric furnace 11 and drawn into a fiber, which is wound around a bobbin. Thus, a single-mode optical fluoride fiber having a core of a small diameter is easily obtd. The fiber can be used as a single- mode waveguide in the wavelength range of 2-4mum, the ratio in diameter between the core and clad of the fiber is 1:>=5, and the fiber has such strength as to fit for handling.

    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.
