ABSTRACT:
A microstructured optical fiber is structured with a core region and a cladding region surrounding the core region. A cross section of the fiber portion conforms to a translationally symmetric lattice, a center of each sub medium region in the outer region coinciding with respective lattice points, and a plurality of sub medium regions in the inner region having centers that are offset from respective lattice points.
