Recently, widely broadened supercontinuum (SC) has been generated using ultrashort pulse and highly nonlinear fibers. However, inherent noise and fine structures have been the problem for the application of SC. We demonstrate wideband, low-noise, highly coherent, and ultraflat SC generation using soliton pulse and normal dispersion highly nonlinear fibers. Characteristics of generated SC are experimentally evaluated, and they are compared with those of the conventional SC. Octave spanning high-quality SC is also generated using high-power soliton pulse.
