Abstract:Abstract-Novel single radial/azimuthal mode photonic crystal fibers (PCFs) with an anisotropic elliptical-hole lattice core (EHLC) are proposed and demonstrated numerically. High birefringence is achieved by introducing elliptical holes into the core, which is considered as an effective way to break the symmetry. With a full vectorial finite element method, we can optimize the fiber parameters and also investigate the wave guiding characteristics in detail. A bandwidth of 210 nm (the wavelength range from 1.45… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
