Abstract
A micro-structured optical fiber precursor is made by size reducing a multiple core optical fiber having solid multiple cores or a multiple core optical fiber preform O having multiple solid core preforms C. A fiber fuse is induced in at least one of the cores of the precursor . The effect of the fiber fuse is to consume the core along the whole length of the fiber or to consume periodically spaced lengths of core along the whole length of the fiber.
