Author Affiliations +
This paper describes a numerical method of accurately modeling large pitch rod type photonic crystal fiber amplifiers taking into account a converged solution to the thermo-optic feedback loop. This method also accounts for the possibility of asymmetric doping profiles and directly treats higher order mode stimulated thermal Rayleigh scattering gain competition along the entire length of the amplifier. Example applications are described. This approach enables further fiber design optimization to increase peak and average amplifier power outputs.
