ABSTRACT:
The invention relates to a micro-structured fiber comprising a core region and a cladding region. The cladding region has a plurality of air holes regularly arranged on a plurality of rings, wherein the innermost ring of the fiber defines the core region. The cladding region comprises an inner circumference portion and an outer circumference portion; the inner circumference portion comprises at least one ring, the outer circumference portion comprises at least one ring, wherein the diameter of the air hole on the outer circumference portion is larger than that of the air hole on the inner circumference portion. As a result, the micro-structured fiber of the present invention has the advantages of broader band of nearly zero dispersion, less confinement loss, being easier to design due to less geometrical parameters needed to be optimized, and being easier to fabricate.
