利用一种新型的马赫-曾德尔（SMZ）型光开关实现了168 Gb/s的无差错全光波长转换，这是迄今为止报道的最高重复频率。低功耗惩罚84 Gb/s的操作也被证明。SMZ开关的推挽式开关机制基于与半导体光放大器中的载流子耗尽相关联的交叉相位调制来实现这种超快操作。延迟干涉信号波长转换器的配置，这是一个简化的SMZ开关的变体，在这个实验中使用。
Error-free all-optical wavelength conversion at 168 Gb/s, which is the highest repetition rate ever reported, has been achieved by using a symmetric-Mach-Zehnder (SMZ)-type switch. Low-power-penalty 84-Gb/s operation is also demonstrated. The push-pull switching mechanism of the SMZ switch enables such ultrafast operation based on cross-phase modulation associated with the carrier depletion in a semiconductor optical amplifier. The configuration of the delayed-interference signal-wavelength converter, which is a simplified variant of the SMZ switch, is used in this experiment.
