摘要

以前我们已经开发了一种使用Ti:LiNbO3相交波导的双极压控光开关[1]。图1显示了用Z-cut Ti:LiNbO3制备的双极压控光开关(bipolar switch)的结构示意图和典型调制特性。与Δβ-reversal型定向耦合器开关相比，双极开关具有缩短开关元件长度和简化多通道集成的优点[2]。

Integrated Optic Switching Circuit Using Ti:LiNbO3 Waveguide Network

Previously we have developed a bipolar-voltage-controlled optical switch using Ti:LiNbO3 intersecting waveguides [1]. Figure 1 shows the schematic structure and typical modulation characteristics of bipolar-voltage-controlled optical switch (bipolar switch) fabricated in Z-cut Ti:LiNbO3. The bipolar switch has the advantage of reduced switch element length and simplified multichannel integration compared with Δβ-reversal type directional coupler switch [2].
