Abstract

By performing an ultrafast pump-probe experiment, we demonstrate the adiabatic frequency conversion of a telecommunications pulse in a silicon photonic crystal waveguide. By using slow-light modes to spatially compress the pulse, a 1.3 ps long pulse is blue-shifted by 0.3 THz with 80% efficiency in a waveguide just 19 μm long. We also present the results of an adiabatic model of the process, which agrees excellently with the experimentally measured data.
