本文报道了 160 Gb/s 光时分复用 (OTDM) 技术，包括提供全通道独立调制的全光集成复用器 (MUX)、提供全通道同时解复用的全光集成解复用器 (DEMUX) 以及用于超高速 OTDM 信号的无漂移锁相环 (PLL) 型时钟恢复电路。我们介绍了每种技术的配置以及这些技术的实验结果。通过使用基于周期性极化铌酸锂（PPLN）混合集成平面光波电路（PLC）的MUX、基于半导体光放大器混合集成PLC的DEMUX以及基于具有光相位调制器和PPLN波导的PLL的时钟恢复电路，成功地证明了高度稳定的操作
This paper reports 160-Gb/s optical time-division-multiplexed (OTDM) technologies including an all-optical integrated multiplexer (MUX) providing all-channel independent modulation, an all-optical integrated demultiplexer (DEMUX) that offers all-channel simultaneous demultiplexing, and a drift-free phase-locked-loop (PLL)-type clock recovery circuit for ultrahigh-speed OTDM signals. We present the configuration of each technology and the results of experiments on those technologies. Highly stable operation is successfully demonstrated by using a MUX based on periodically-poled lithium niobate (PPLN) hybrid integrated planer lightwave circuit (PLC), a DEMUX based on semiconductor optical amplifier hybrid integrated PLC, and clock recovery circuit based on a PLL with an optical phase modulator and a PPLN waveguide
