论文摘要
我们提出了一种新型的生物传播结构，该结构由插槽双 - 微环谐振器和单层石墨烯组成。基于电磁诱导的透明度（EIT） - 样现象和石墨烯的光吸收特征，我们呈现出辅助模式理论和kubo模式的理论分析。配置文件。基于有限差异时域（FDTD）方法获得的传输光谱的模式场分布。您的生物传感器具有330nm/riU的理论敏感性，最小检测极限，最小的3600RIU检测限，最大的灭绝率，最大值的4.4DB，4.4DB的最大灭绝率，是1288和1288的质量。生物传感器的性能是为葡萄糖溶液模拟的。我们所提出的设计为与其他硅光子元件进行芯片整合提供了有希望的候选者。
We propose a novel bio-sensor structure composed of slot dual-micro-ring resonators and mono-layer graphene.Based on the electromagnetically induced transparency (EIT)-like phenomenon and the light-absorption characteristics of graphene,we present a theoretical analysis of transmission by using the coupled mode theory and Kubo formula.The results demonstrate the EIT-like spectrum with asymmetric line profile.The mode-field distributions of transmission spectrum obtained from 3D simulations based on finite-difference time-domain (FDTD) method.Our bio-sensor exhibit theoretical sensitivity of 330nm/RIU, a minimum detection limit of 3600RIU,the maximum extinction ratio of 4.4dB,the quality factor of 1288 and a compact structure of 15um*10um.Finally, the bio-sensor's performance is simulated for glucose solution.Our proposed design provide a promising candidate for on-chip integration with other silicon photonic element.
