In this paper we aim to propose and design an all optical analog to digital converter for generating 2-bit Gray codes from the optical intensity of the input signal. Two nonlinear resonant rings will be used for realizing the proposed structure. These nonlinear resonators should be designed such that they can drop optical waves at different optical intensity ranges. The nonlinear resonators will be created by adding some nonlinear rods between the outer rods and the core rods. According to the simulation results the rise time for the proposed structure is about 2 ps.

基于PhC的OADC格雷码生成的新建议

在本文中，我们旨在提出并设计一种全光模数转换器，以根据输入信号的光强度生成2位格雷码。两个非线性谐振环将用于实现所提出的结构。这些非线性谐振器的设计应使其能够在不同的光强度范围内使光波掉落。非线性谐振器将通过在外部棒和芯棒之间添加一些非线性棒来创建。根据仿真结果，所提出结构的上升时间约为2 ps。
