摘　　要：光存储系统是未来全光通信和全光计算的关键要素。基于有限元方法的仿真实验研究,设计了一种新型的光学存储系统,该系统基于磁光光子晶体单向边界模式与微腔模式的耦合。应用磁光光子晶体单向边界模式特性形成闭合回路。设计另外的单向波导和磁性微腔,电磁信号不仅能从闭合回路中取出,而且能写入回路。通过外加磁场控制微腔属性,可动态实现电磁信号的读写操作。Optical storage system is the key role for the future all-optical communications and computer. Through numerical study, we design a new kind of magneto-optical storage system based on the coupling of one-way edge modes of magneto-optical photonic crystals and microcavity modes. A close field circulation loop is achieved from the one-way edge modes. By designing a magnetic cavity and another edge waveguide, we can not only take out the signal from the loop but also write the signal into the loop. Through controlling the magnetic field on the cavity, we can dynamically achieve the operation of reading and writing of electromagnetic signals.
