In the advanced plasmonics integrated circuits (PICs) there has been outstanding, continuing interest in developing routers to harness light-matter interactions in nanoscale dimensions with wanted optical properties. In this regard, herein, we introduce an all-optical router based on nanometer ring resonator which surface plasmon resonance (SPR) and nonlinear materials are used simultaneously to enhance high performance range. By changing the radius of the ring resonator and the intensity of the light we achieved control of the parameters and the routing. The results of routing and shifting the central frequency with light intensity and radius of the ring resonator are studied. The performance of the router indicates that a ring is required for each ports, which changes the control parameters to change its central frequency, as well as we can be said the use of switches and filters as other design features. These routers have advantages such as nano scale size, low light intensity, fast response time, integratable and etc., which are highly used in all-optical circuits, image processing and today's modern technology. In our simulation, we consider transmission or reflection of light in each ports based on the finite difference time domain (FDTD).

在先进的等离子体集成电路 (PIC) 中，人们一直对开发路由器以利用具有所需光学特性的纳米级光物质相互作用产生了浓厚的兴趣。在这方面，我们在此介绍了一种基于纳米环形谐振器的全光路由器，它同时使用表面等离子体共振 (SPR) 和非线性材料来增强高性能范围。通过改变环形谐振器的半径和光强度，我们实现了对参数和路由的控制。研究了中心频率随光强和环形谐振器半径的路由和偏移的结果。路由器的性能表明每个端口都需要一个环，通过改变控制参数来改变它的中心频率，以及我们可以说使用开关和滤波器作为其他设计特征。这些路由器具有纳米级尺寸、低光强、响应时间快、可集成等优点，在全光电路、图像处理和当今现代技术中得到广泛应用。在我们的模拟中，我们基于有限差分时域 (FDTD) 考虑每个端口中光的传输或反射。
