Abstract The all-optical logic gates have become an important key enabling in optical integrated circuits and find applications in optical networks. In this paper, we introduce new complete series of optical logic gates using photonic crystals. These designs formed by compilation with interference based defect and resonance phenomenon. The proposed work based on two dimensional square lattices by putting gallium arsenide (GaAs) rods immersed on air background. The maximum contrast ratio and the maximum working bit rates is obtained for the NOT/XOR and OR logic gates equal to 50.81 dB and 12.5 Tb/s, respectively. The simulation and optimization of structure is approved out using Finite-Difference-Time-Domain (FDTD) method and Plane Wave’s Method (PWEM).

基于光子晶体环谐振器的全设计光学逻辑门的高对比度

摘要 全光逻辑门已成为光集成电路的重要使能关键，并在光网络中得到应用。在本文中，我们介绍了使用光子晶体的新的完整系列的光逻辑门。这些设计由基于干扰的缺陷和共振现象编译而成。拟议的工作基于二维方形晶格，通过将砷化镓 (GaAs) 棒浸入空气背景中。NOT/XOR 和 OR 逻辑门的最大对比度和最大工作比特率分别等于 50.81 dB 和 12.5 Tb/s。使用有限差分时域（FDTD）方法和平面波方法（PWEM）进行了结构的模拟和优化。
