我们提出并演示了在波长和时间域中以细粒度进行的数据交换，即，波分复用高速光时分复用信号的低速支路信道交换。利用周期性极化的双金属锂（PPLN）波导中级联的二阶非线性相互作用的参量耗尽效应，在实验上实现了10 Gbit/s的支路信道交换，在误码率为10（-9）的条件下，两个160 Gbit/s信号的功率代价小于4 dB.此外，考虑到波导传播损耗，我们推导出解析解，调查的信号损耗（SD）和消光比（ER）性能的PPLN为基础的数据交换。理论分析表明，低的波导传播损耗有利于获得大的SD和ER。
We propose and demonstrate data exchange in both the wavelength and time domains at a fine granularity, i.e., low-speed tributary channel exchange of wavelength-division multiplexed high-speed optical time-division multiplexed signals. Using the parametric depletion effect of cascaded second-order nonlinear interactions in a periodically poled lithium niobate (PPLN) waveguide, we experimentally implement 10 Gbit/s tributary channel exchange between two 160 Gbit/s signals with a power penalty of less than 4 dB at a bit-error rate of 10(-9). Moreover, taking into account the waveguide propagation loss, we derive analytical solutions to investigate the signal depletion (SD) and extinction ratio (ER) performance of the PPLN-based data exchange. The theoretical analyses indicate that low waveguide propagation loss benefits large achievable SD and ER.
