提出了一种基于相位调制和光谱滤波的光电时分解复用方案。相位调制的频率是光信号比特率的四分之一。因此，我们的方案是适用于160-Gbit/s的系统，只需使用一个商用的40-GHz的铌酸锂（3）相位调制器和光学滤波器。当160 Gbit/s信号被解复用时，所有支路的功率损失小于2 dB。
We propose an optoelectronic time-division demultiplexing scheme based on phase modulation and spectral filtering. The frequency of phase modulation is quarter the bit rate of the optical signal. Therefore, our scheme is applicable to 160-Gbit/s systems by using only a commercially available 40-GHz LiNbO(3) phase modulator and optical filter. The power penalties are less than 2 dB for all tributaries, when a 160-Gbit/s signal is demultiplexed by our scheme.
