Simulation-Based Parametric Optimization of Optical Ring Resonators for Potential Biomedical Biosensing Applications

Biosensors have become indispensable tools in modern diagnostics, offering high sensitivity and specificity for the detection of biological and chemical substances. Among various biosensing techniques, optical resonator-based biosensors provide a promising alternative because of their enhanced performance metrics, including high-quality factors and precise wavelength shift detection. This study presents a simulation-based investigation focused on the parametric optimization of optical ring resonator structures for biomedical applications. Although experimental validation with biomolecules has not yet been conducted, the simulated designs demonstrated high quality factors and sensitivity to refractive index changes. These results suggest the potential for integration into compact and efficient biosensing platforms in future implementation in biomedical diagnostics.
