    Abstract: To overcome problems of fabricating conventional core-clad optical fibre from non-silica based (compound) glass, it is proposed to fabricate non-silica based (compound) glass optical fibre as holey fibre i.e. one contining Longitudinal holes in the cladding. This removes the conventional problems associated with mismatch of the physical properties of the core and clad compound glasses, since a holey fibre can be made of a single glass composition. With a holey fibre, it is not necessary to have different glasses for the core and cladding, since the necessary refractive index modulation between core and cladding is provided by the microstructure of the clad, i.e. its holes, rather than by a difference in materials properties between the clad and core glasses. Specifically, the conventional thermal mismatch problems between core and clad are circumvented. A variety of fibre types can be fabricated from non-silica based (compounds) glasses, for example: single-mode fibre; photonic band gap fibre; highly non-linear fibre; fibre with photosensitivity written gratings and other refractive index profile structures; and rare-earth doped fibres (e.g. Er, Nd, Pr) to provide gain media for fibre amplifiers and lasers.

    Abstract translation: 为了克服从非二氧化硅（复合）玻璃制造常规的包芯光纤的问题，提出了制造非二氧化硅基（复合）玻璃光纤作为多孔纤维，即在包层中连续的纵向孔。 这消除了与芯和包覆复合玻璃的物理性质失配相关的常规问题，因为多孔纤维可以由单一玻璃组合物制成。 使用多孔光纤，由于芯和包层之间必需的折射率调制由包层的微结构即其孔提供，而不是通过材料性质的差异来提供用于芯和包层的不同的玻璃。 在包层和核心眼镜之间。 具体来说，芯和包层之间常规的热失配问题被规避。 各种纤维类型可以由非二氧化硅（化合物）玻璃制成，例如：单模纤维; 光子带隙光纤; 高度非线性的纤维; 具有光敏写入光栅的纤维和其他折射率分布结构; 和稀土掺杂光纤（例如Er，Nd，Pr），为光纤放大器和激光器提供增益介质。

    Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a columnar glass body which has a plurality of areas continuing in the longitudinal direction and having a high heavy ion concentration; and a method for producing an optical fiber having a plurality of cores. SOLUTION: A columnar glass body which has a plurality of areas continuing in the longitudinal direction and having a high heavy ion concentration is produced as follows: a heavy ion in a thin beam state is implanted at a specified position in a long columnar glass body to form an area with a high heavy ion concentration; by successively changing the relative positions of an ion accelerator and the columnar glass body in the longitudinal direction of the columnar glass body, the heavy ion in a thin beam state is successively implanted into the columnar glass body to form an area continuing in the longitudinal direction and having a high heavy ion concentration; and the above operations are repeated at least twice at other positions in the columnar glass body to form a plurality of areas continuing in the longitudinal direction and having a high heavy ion concentration. An optical fiber having a plurality of cores is produced by subjecting the columnar glass body having a plurality of areas continuing in the longitudinal direction and having a high heavy ion concentration to a drawing treatment in the longitudinal direction.
