Comparison of Nonlinear Properties in Silica-Core and Hollow-Core Fibers

Abstract

Hollow-core photonic bandgap fibers exhibit nonlinear properties. In comparison with conventional silica-core optical fibers, we experimentally evaluate whether the hollow-core photonic bandgap fiber has extremely low nonlinearity compared with silica-core optical fibers in terms of stimulated Brillouin scattering and four-wave mixing. A low nonlinearity is useful for high-power optical transmission applications.
