Mikrostrukturierte Lichtwellenleiter und Herstellungsmethode

摘要

A microstructured optical fiber is structured with a core region (11a) and a cladding region (12a) surrounding the core region. A cross section of the fiber portion conforms to a translationally symmetric lattice (4a), a center of each sub medium region in the outer region (32a) coinciding with respective lattice points, and a plurality of sub medium regions in the inner region (35a) having centers that are offset from respective lattice points.
