提出了一种由两个平行放置的周期调制非线性光波导组成的全光开关。与传统的基于非线性定向耦合器的无周期调制全光开关相比，该全光开关具有更低的开关阈值功率和更窄的开关宽度。
We propose a type of all-optical switch which consists of two periodically modulated nonlinear optical waveguides placed in parallel. Compared to the all-optical switch based on the traditional nonlinear directional coupler without periodic modulation, this all-optical switch has much lower switching threshold power and sharper switching width.
