摘要

A 21.7-km nonzero dispersion-shifted fiber was used to obtain 4x multiplication of the repetition rate of a 20-GHz train of 4.2-ps optical pulses through the temporal Talbot effect. Raman compression in the same fiber shortened and developed the pulses into 2.0-ps solitons and resulted in a lower duty cycle. It is shown that the linear Talbot effect and nonlinear Raman compression occurred in different sections of the fiber, the lengths of which could be varied through adjustments in the input pulse power.
