摘要

本文提出了一种高性能的光子滤波器和等离子体传感器。首先，滤波器结构由一个不对称的1D环（环）和六个对称谐振器组成。通过控制一维结构的几何参数，实现了最优滤波。在此背景下，结果显示在GHz范围内出现三种共振模式，几何参数以毫米为单位，具有高传输速率和高质量因子等高性能。其次，研究了基于MIM的二维等离子体结构在可见光范围内作为折射率等离子体传感器。灵敏度达912.3 nm/RIU，检出限DL = 0.005 RIU。

Impact of geometric and optical parameters on the properties of a loop structure with resonator: Applications to filtering and sensing

This work, present a high-performance photonic filter and plasmonic sensor. Firstly, the filter configuration consists of an asymmetrical 1D loop (ring) and six symmetrical resonators. The optimum filter is achieved by controlling the geometrical parameters of the 1D structure. In this context, the results present the appearance three resonance modes in the GHz range frequency and geometrical parameters in millimeters, with high performances such as transmission rate and high quality factors. Secondly, a 2D plasmonic structure based on MIM is investigated as a refractive index plasmonic sensor in the visible range. The sensitivity of this device reaches 912.3 nm/RIU and the detection limit DL = 0.005 RIU.
