ABSTRACT:
A method for manufacturing a photonic crystal fiber including arranging a spacer formed of two or more spacer parts in a support tube such that the inner wall surface of the support tube has a substantially regular polygonal cross-sectional shape which allows closest packing of a core rod and a plurality of capillaries or the capillaries only; and forming a preform by packing in a support tube the core rod for forming a solid core and the capillaries for forming a cladding, or by providing a core space for forming a hollow core in a support tube and packing in the support tube a plurality of capillaries for forming the cladding; and drawing the preform into a fiber under heating.
