摘要： This invention relates to a method of preparing a preform for an optical fibre, and more particularly to a method of preparing a preform for a polymer holey optical fibre. The invention provides a method of preparing a preform for manufacture of a polymer holey optical fibre comprising casting a preform body in a mould from a suitable material, said mould including at least one protrusion adapted to form a corresponding hole within the preform, and subsequently separating the preform body and mould. The invention also provides a method of preparing a preform for manufacture of a polymeric holey optical fibre comprising separately casting one or more elements of a preform in respective mould(s) from a suitable material, and separating said elements from said respective mould(s) and combining said elements to construct a preform having a plurality of holes therein, each hole being formed in an element or formed by the combination of two or more elements.

摘要： This invention provides an optical fibre (1) incorporating a body (2), and an array of longitudinally extending holes or inclusions (3) formed in the body (2), the holes or inclusions (3) having a different refractive index from the surrounding body (2) and being arranged to form a full or partial ring structure (5) extending generally around a longitudinal axis of the fibre, the ring structure (5) being disposed so as to approximate the refractive or reflective transmission characteristics of a multi−layer optical fibre. The fibre (1) may have a solid core or a hollow air core. The invention also provides a method of forming the microstructured optical fibre (1).
