论文摘要
在本文中,提出了基于金属绝缘体 - 金属(MIM)波导的双侧不对称等边相线环(ETR)带滤波器。滤波器的传输光谱和电场分布模拟,理论上通过有限的差异时间域(FDTD)和耦合模式理论(CMT)方法对滤波器进行了研究。结果表明,更改谐振腔的数量和位置可以调整过滤器的传输特性。该过滤器的最小传输和灵敏度分别为0.19%和1149 nm/riU。过滤器在高度集成的光电电路和折射率传感器中具有广泛的前景。
In this paper, a bilateral asymmetric equilateral triangular ring (ETR) band-stop filter based on metal-insulator-metal (MIM) waveguide is proposed. The transmission spectrum and electric field distribution of the filter are simulated and theoretically investigated by finite difference time domain (FDTD) and coupled mode theory (CMT) method. The results show that changing the number and position of resonant cavities can adjust the transmission characteristics of the filter. The minimum transmission and sensitivity of this filter is 0.19% and 1149 nm/RIU, respectively. The filters have broad prospects in the highly integrated optical circuits and refractive index sensor.
