快速磁响应光子晶体的研究进展

摘要

Responsive photonic crystals are dielectric materials which are periodic arrangement of different mediums,among which magnetically responsive photonic crystals (MRPCs) are developing fast in recent years because of their rapid response to the change of external magnetic field and transform into optical signal. This paper presented the research progress in MRPCs. Firstly,the principle of photonic band gap produced by MRPCs under the effect of external magnetic field is described on the basis of Bragg’s law. Secondly,different synthetic pathways for fast MRPCs are concluded. On the basis of rapid responsive MRPCs,this paper conducted a comprehensive analysis in various aspects,such as the stabilizing effect,controlling and influencing the shape size and band gap distribution. Finally,it also discussed potential applications of MRPCs in sensors,security,color printing and other areas.%响应性光子晶体是由不同介质周期性排列组成的带隙介质材料，其中磁响应光子晶体因为能将外界磁场强弱变化快速表达为光学信号而在近几年发展迅速。本文从理论到具体工作综合论述了快速磁响应光子晶体的研究进展。首先基于布拉格衍射定律介绍了磁响应光子晶体在外部磁场的作用下产生光子带隙的原理，然后系统总结了该类光子晶体的不同合成途径，并在其能快速响应的基础上从稳定效果、形态尺寸控制和带隙分布等方面进行了综合分析，最后从应用上探讨了具有快速磁响应特性的光子晶体对于传感器、防伪、彩色印刷等领域的潜力。
