Micro-Ring Resonator-Based Sensors for Detection of Different Chemicals

The sensing of different liquids is investigated with micro-ring resonator (MRR) sensor by changing refractive index (RI) of chemical solutions. Aniline, carbon disulphide, chlorobenzene, chloroform, ethanol, glycerin, and methanol are detected using the proposed MRR. The developed structures are simulated using finite difference-time domain (FDTD) by using DFT analyzer of optical field. The normalized amplitude vs. wavelength is measured by changing RI of inner ring waveguide that obtain liquid sensor with high sensitivity.
