Abstract

A new class of optical fiber has recently emerged which shows considerable promise; holey fibers have highly tailorable optical properties arising from their design flexibility [1, 2]. Typically holey fibers (HFs) are made from undoped silica, and have a cladding region formed by air holes running along the fiber length. The holes are often arranged in a periodic lattice [as in Fig. 1 (a)], and the core is formed by an absent air hole.
