However, since the guided mode in an EC-CHF has a polarization that arises from large geometrical anisotropy of the core lattice, the influence of the bending direction on the bending loss is a crucial issue for the practical implementation of EC-CHFs.Here, the bending losses of an EC-CHF bent in arbitrary angular orientations with respect to the core cross section are calculated numerically using the equivalent anisotropic step-index circular fiber model for a real EC-CHF and the influence of the bending direction of the fiber on the bending loss is discussed.}, pages = {6207--6212}, title = {Bending loss of elliptical-hole core circular-hole holey fibers bent in arbitrary bending directions}, volume = {49}, year = {2010}, yomi = {エグチ, マサシ and ツジ, ヤスヒデ} }
