1.9 ps optical switching at 40 GHz repetition rate has been successfully demonstrated in submicron-size silicon wire waveguides. Ultrafast operation is achieved by induced optical absorption from two-photon absorption (TPA) process. The device requires very low energy, less than 3 pJ, to accomplish 92% of modulation depth.
