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 320 Gbit/s is measured for the extracted 40 Gbit/s tributaries with a 3.4 dB average power penalty to the original signal.
在这项研究中，我们通过量子点半导体光放大器中的四波混频实现了超高速度强度调制信号的无误全光波长转换。对于提取出的 40Gbit/s 支路，在 320Gbit/s 的比特率下测量到无误性能，与原始信号相比平均功率代价为 3.4dB。
