Abstract
We demonstrate four-wave mixing in silicon-on-insulator coupled-resonator optical waveguides consisting of 35 and 65 microring resonators, using a cw pump with coupled power below and observed parametric conversion across more than . The conversion efficiency is enhanced by relative to a silicon straight waveguide of equivalent length, due to the slowing factor of the coupled-resonator structure.
