摘要

本文演示了一种紧凑的微米尺寸的三不对称微环谐振器（TUMRR），该谐振器采用基于游标效应的光学滤波器和基于高灵敏度折射率（RI）的生物传感器，用于癌细胞检测。利用MATLAB对双功能TUMRR滤光片进行了仿真分析，并在OptiFDTD软件中得到了折射率变化技术检测癌细胞的灵敏度结果。所提出的结构可以作为1 × 3输入输出光滤波器，以解决高FSR和q值。利用延迟线信号处理进行数学建模，以获得用于滤波器分析的传递函数，其中单位延迟建模为z−1。得到Tf1、Tf2和tf3的fsr分别为315 THz、615 THz和835 THz， q因子分别为842、1338和2200。该传感器结构的灵敏度范围为150.3 ~ 167 nm/ RIU。

Dual-function analysis of triple unsymmetrical microring resonators for biosensor and optical filter applications

In this paper, a compact micron-sized triple unsymmetrical microring resonator (TUMRR) using the Vernier effect based optical filter and highly sensitive refractive index (RI) based biosensor for cancer cells detection has been demonstrated. The simulation analysis of dual-function TUMRR as an optical filter is done using MATLAB, and the sensitivity results for cancer cell detection using the refractive index change technique have been obtained in OptiFDTD software. The proposed structure may act as a 1 × 3 input-output optical filter to address high FSR and Q-value. Mathematical modeling to obtain the transfer function for filter analysis is done using delay line signal processing, where a unit delay is modeled as

z^{- 1}

. The obtained FSRs for

{Tf}_{1}, {Tf}_{2}, and {Tf}_{3}

are 315 THz, 615 THz, and 835 THz, and the Q-factors are 842, 1338, and 2200, respectively. The reported sensitivity range of the proposed sensor structure is from 150.3 to 167 nm/ RIU.
