Abstract
In this paper, the dispersion coefficients and the nonlinear parameter of a wagon wheel fiber is obtained by finite element method. Efficient broadband near infrared supercontinuum generation is predicted in a 15 cm of the single-mode small core silicon wagon wheel fiber by solving the generalized nonlinear Schrödinger equation when the fiber is pumped by femtosecond pulses in the abnormal dispersion regime. Here, it is shown that the flattened supercontinuum spectrum over 850 nm wide is achieved.
