Suppression of Higher-Order Modes by Segmented Core Doping in Rod-Type Photonic Crystal Fibers

A large mode area Yb-doped rod-type photonic crystal fiber design with a low refractive index ring in the core is proposed to provide an improved suppression of the first higher-order mode compared to the case of uniform core doping, in a way which is more robust against fluctuations in the refracti...
