Characteristics of Resonantly-Guided Modes in Microstructured Optical Fibers
Modal characteristics of resonantly-guided modes (RGMs) in microstructured fibers were investigated through numerical simulation. The modes of interest are supported in a class of fibers consisting of a circularly arranged periodic array of high index ...
