A format conversion from a non-return-to-zero (NRZ) signal to return-to-zero (RZ) signal is presented based on four-wave mixing (FWM) and cross-phase modulation (XPM) in a silicon optical waveguide.

基于硅光波导的四波混频(FWM)和交叉相位调制(XPM)效应，提出非归零码(NRZ)到归零码(RZ)的光调制格式转换。

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。

All right. I want to return to some non-scalar types. So we've been looking, the last couple of lectures, at floating pointing numbers and integers.

好，我们现在回到一些,非基本类型的话题来，我们在过去的几节课里,一直在研究浮点数类型和integer类型。

There is an open question as to whether the courts of a non-DAPT state can compel the return of asset from the DAPT state to the non-DAPT state so that those assets are available to creditors, i.e.

Where it gets interesting is where the Debtor has assets in the DAPT state, but under the terms of the trust document, the Debtor has no ability to return them to the non-DAPT state where he resides.
