Supercontinuum generation without residual pump peak through multiple coherent pump seeds

We report an enhanced supercontinuum generation (SCG) in a conventional highly nonlinear fiber through injecting double bound-state solitons, which eliminates the residual pump peak existing in conventional SCG. The use of these phase-locked pulse pairs yields a novel multiple coherent pump techniqu...

Summary:We report an enhanced supercontinuum generation (SCG) in a conventional highly nonlinear fiber through injecting double bound-state solitons, which eliminates the residual pump peak existing in conventional SCG. The use of these phase-locked pulse pairs yields a novel multiple coherent pump technique. We further compare the SCGs pumped by conventional bound-state soliton and single-soliton. It confirms that the effective elimination of the residual pump peak in supercontinuum owes to higher transferring efficiency of the pump energy to newly generated frequencies in the multiple coherent pump scheme. The obtained results provide a new and simple method to obtain a flat supercontinuum source.
