All-optical switching and wide-range wavelength conversion have been demonstrated at 160 Gbit/s using four-wave mixing in a semiconductor optical amplifier. We used the asymmetrical multiple-quantum-well semiconductor optical amplifier which allows for a wide 3 dB gain-bandwidth. The cross-correlation measurements show the high-speed switching capability for wavelength routing in optical time division multiplexing networks.
