摘要：
In this paper, we have designed a refractive index RI sensor based on optical fiber micro-ring resonator for water analysis. Where, we have used the Finite Element Method (FEM) to simulate our design. To Asses the effects of the ideal sensor's material, we have investigated a comparative study between the two popular materials PMMA and the Silicon, plying on the set of common performance parameters: sensitivity, FWHM, quality factor and Limit of detection(LOD). As a result, we have found that The PMMA material has attended a maximum sensitivity equal to 763:5nm/RIU. However, the best quality factor and LOD are achived by the silicon material that are respectively given 70300 and 3.79 x 10(-4) and ultra narrow FWHM (0.024).
