Experimental demonstration of widely tunable wavelength conversion between ps-pulses based on four-wave mixing in cascaded highly nonlinear fiber

摘要

Widely tunable All-optical wavelength conversion between picoseconds pulses based on Four-wave mixing is proposed and experimentally demonstrated in cascaded highly nonlinear fiber. The signal pulse with 40-GHz repetition rate and 1.57-ps pulse width is adopted. The converted idler wavelength can be tuned continuously from 1540.6 to 1594.8 nm as the CW laser wavelength is changed from 1514.5 to 1565.7 nm. No obvious changes of the pulse shape and width, also no chirp are observed in the converted idler pulse.
