The MZM is driven by a non-return-to-zero (NRZ) data sequence and biased at the nonlinear point to generate edge-triggered pulses.

利用双输出口调制器典型的互补输出特性，通过偏置调制器于非线性传输点，可得到一对由NRZ序列边沿触发的明暗脉冲。

And varied capacitor electrode structures of silicon MZM may make the visible difference of the modulation performance, including the rise and fall time.

当改变该调制器结构参数后，其上升时间和下降时间会产生明显变化。
