针对双信道偏振复用保密通信系统，利用线性电光效应，提出了一种新的完全混沌同步的控制方案. 在该方案中，每一个线性偏振模的完全混沌同步质量随外加电场成准周期性变化. 其变化规律：完全混沌同步 ↔ 剧烈振荡；固定一定的外加电场，电光调制促使其完全混沌同步质量对偏置电流和反馈强度的稳健性获得极大的加强. 在较大的偏置电流和反馈强度范围内，每一个线性偏振模能够实现完全混沌同步，并且调制到每一个线性偏振模的加密信号基本上能够恢复.

For the dual-channel encryption system, based on polarization-division-multiplexing, we put forward a new control scheme for complete chaos synchronization by means of linear electro-optic (EO) effect. In the scheme, the chaotic synchronization quality of each linear polarization (LP) mode component varies periodically with the applied electric field. The variation regulation is as follows: Complete chaos synchronization ↔ acute oscillation. With the applied electric field fixed at a certain value, the robustness of the complete chaotic synchronization quality due to the bias current and the feedback strength is improved greatly by EO modulation. Each LP mode can obtain the complete chaos synchronization in a large range of the bias current and the feedback strength. And the encoding message modulated to each LP mode can be almost re-established.-
