摘要:
基于光子晶体的局域特性与禁带特性,提出了一维环形镜像缺陷态光子晶体结构。镜像结构的引入将在光子晶体的中心处形成缺陷腔,从而在透射光谱禁带中获得谐振透射峰。利用传输矩阵法建立谐振峰值波长与待测样本参数之间的传感模型。将原波导结构中的介质B挖空形成环形空气凹槽从而可得到改进后的环形镜像空气栅光子晶体结构,进而通过观测谐振峰值波长的漂移来实现气体样本参数的动态监测。仿真结果表明,结构的传感Q值可达1 739.48,灵敏度约1 642 nm·RIU-1,证实了该传感结构的有效性。该结构可为空气污染监测和气体成分分析提供一定的理论依据。
Abstract:
Based on the photonic localization and the photonic characteristics of photonic crystals,one-dimensional ring mirror defect photonic crystal structure is proposed.Due to the introduction of mirror structure,a defect cavity is formed in the middle of the photonic crystal,and then the resonant transmission peak can be obtained in the forbidden band of transmission spectrum.The transfer matrix method is used to establish the relationship model between the resonant transmission peak and the structure parameters of the photonic crystals.Using the rectangular air gate photonic crystal structure,the dynamic monitoring of the detected gas sample parameters can be achieved from the shift of the resonant transmission peak.The simulation results show that the Q value can attain to 1 739.48 and the sensitivity can attain to 1 642 nm·RIU-1,which demonstrates the effectiveness of the sensing structure.The structure can provide certain theoretical reference for air pollution monitoring and gas component analysis.
