一维环形镜像缺陷态光子晶体结构传感特性研究
Study on refractive index sensing property of one-dimensional ring mirror defect photonic crystal structure
摘要
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.关键词
