摘要
基于二维磁光光子晶体和拓扑光子学理论,提出一种新的光路传输网络结构,其由一系列光子晶体和空气的矩形单元组成。首先根据施加正向磁场、负向磁场和空气区域的三种情况分别标记为“+1”、“-1”和“0”并将其作为编码单元。然后构建2×2、3×3和4×4三种光路矩阵网络。最后利用COMSOL软件模拟光波的传输路径。仿真结果表明,通过不同的编码序列可以对光路实现灵活和多样的控制,从而在未来光集成回路中满足高密度光路传输和大容量信息处理的要求。
Abstract
A new optical transmission network structure is proposed based on the two-dimensional magneto-optical photonic crystal and topological photonics theory, which is composed of a series of rectangular photonic crystals and air. To create coding units, the three conditions of applying a positive magnetic field, a negative magnetic field, and an air area are marked as “+1”, “-1”, and “0”, respectively. Then, three types of optical path matrix networks of 2×2, 3×3, and 4×4 are constructed. Finally, COMSOL software package is employed to simulate the transmission path of light waves. The simulation results prove that through different coding sequences, flexible and diverse control of the optical path can be achieved. The proposed control fulfils the requirements of high density optical path transmission and large-capacity information processing in the photonic integrated circuits to emerge in the future.
