All-optical comparators play crucial roles in all-optical data processing systems. In this paper, we proposed a novel structure for realizing an all-optical comparator, which can compare two 1-bit binary codes. For this purpose, we used three nonlinear resonant rings. The final structure has two input and three output ports. The maximum rise and fall times for the proposed structure are about 1.5 and 2 ps, respectively.

一种使用非线性PhCRR的全光1位比较器的新建议

全光比较器在全光数据处理系统中起着至关重要的作用。在本文中，我们提出了一种新颖的结构，用于实现可以比较两个1位二进制代码的全光比较器。为此，我们使用了三个非线性谐振环。最终结构具有两个输入端口和三个输出端口。拟议结构的最大上升和下降时间分别约为1.5 ps和2 ps。
