Abstract

In this study, we demonstrate error-free all-optical wavelength conversion of ultrahigh-speed intensity modulated signals by means of four-wave mixing in a quantum-dot semiconductor optical amplifier. Error-free performance at a bit rate of 320Gbit/s is measured for the extracted 40Gbit/s tributaries with a 3.4dB average power penalty to the original signal.
