采用梳状滤波器和半导体光放大器（SOA）相结合的方法对数据信号进行预处理，然后利用SOA注入锁模激光器进行时钟恢复。实验表明，该技术可以有效地减小由时钟脉冲的方向图效应引起的幅度波动和定时抖动。此外，它还表明，时钟可以恢复从非常退化的信号。
A comb-like filter and a semiconductor optical amplifier (SOA) were combined to preprocess the data signals before clock recovery utilizing injection mode-locked laser based on SOA. The amplitude fluctuation and timing jitters caused by the pattern effect in clock pulses were greatly reduced experimentally with this technology. Furthermore, it also demonstrated that clock could be recovered from the very degraded signals.
