We fabricate a two-stage wavelength converter in silicon by cascading a microring wavelength mixer with a five-ring coupled-resonator filter. A p-i-n diode is incorporated into the microring for electronic carrier sweep-out, and microheaters are incorporated into the filter for tunability. The generated idler wavelength is effectively separated from the input pump and signal, with nearly 50 dB of suppression.
