Abstract

We present here, the extensive study of broadband and high parametric gain in highly nonlinear tellurite optical fiber. The chromatic dispersion has been designed to achieve broad gain bandwidth and phase-matching over broad spectral range. The optical parametric gain under pulse repetition rate dependence and with no influence of group velocity gain spectrum has been calculated for different fiber lengths. When the parametric gain was calculated, with dependence on group velocity and repetition rate of pulse, the gain bandwidth was found to be shrinking abruptly due to lessening of pump power. The pulse repetition rate was assumed to be 20 GHz, with fiber core diameter of 0.895 μm and calculated nonlinearity coefficient γ was 6642 W^-1km^-1. The study has been extended to realize the impact of pump power variation over supercontinuum generation with fiber length of 75 cm.
