Abstract

A dispersion-flattened dispersion imbalanced nonlinear optical loop mirror is used to smooth the spectrum and reduce the pedestal of tunable femtosecond solitons generated via pulse compression in a dispersion-flattened dispersion decreasing fiber. Transform-limited pulses with durations less than 210 fs and peak-to-pedestal ratios greater than 40 dB are obtained over a wavelength range of 32 nm at a repetition rate of 10 GHz.
