A novel photonic crystal fiber with a germanium nanoparticles-doped germano-silice te core and its nonlinear optical characteristics

Abstract

A novel photonic crystal fiber with a Ge nanoparticles-doped germano-silicate core was fabricated by using the MCVD and stack-and-draw processes. Effect of Ge nanoparticles and the air-holes structure on non-resonant optical nonlinearity and supercontinuum generation was investigated.
