A 104GHz 328fs soliton pulse train generation through a comb-like dispersion profiled fiber using short high nonlinearity fiber

摘要

We have constructed a 693.6m long comb-like dispersion profiled fiber using a newly developed high-nonlinearity dispersion shifted fiber with nonlinear coefficient that is about five times larger than that of the conventional dispersion shifted fiber. Using this short CDPF, we have generated a 104GHz soliton pulse train with 328fs pulsewidth and the period-to-duration ratio T/△τ (T is the period and △τ is the output pulsewidth) reached 29.3.
