Abstract

Using a 7.5 micron diameter disk fabricated with III-V-on-silicon fabrication technology, we demonstrate a bias-free all-optical wavelength conversion for a non-return to zero on-off keyed pseudo-random bit sequence data at the speed of 10Gbps with an extinction ratio of more than 12dB. The working principle of such a wavelength converter is based on the 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 pseudo-random bit sequence data. All-optical gating measurements in the pump-probe configuration with the same device have revealed that it’s possible to achieve wavelength conversion beyond 20 Gbps.
