Using a 7.5 μm diameter disk fabricated with III-V-on-silicon fabrication technology, we demonstrate bias-free all-optical wavelength conversion for non-return-to-zero on–off keyed pseudorandom bit sequence (PRBS) data at the speed of 10 Gbits / s with an extinction ratio of more than 12 dB . The working principle of such a wavelength converter is based on free-carrier-induced refractive index modulation in a pump–probe configuration. We believe it to be the first bias-free on-chip demonstration of all-optical wavelength conversion using PRBS data. All-optical gating measurements in the pump–probe configuration with the same device have revealed that it is possible to achieve wavelength conversion beyond 20 Gbits / s .
