Design and Analysis of Ring Resonator Embedded with High Contrast Optical Bragg Grating in Z-Domain for Optical Filtering

The integration of ring resonators with Bragg gratings have emerged as promising optical filters because of their compact size and good spectral selectivity. A comprehensive mathematical modeling and analysis of such a system is presented to precisely capture the resonance characteristics and transmission spectra of the system using delay-line signal processing and Z-domain analysis, followed by a discussion on related potential application as well as challenges in modern optical systems. The simulation results indicate improved filtering precision and sharp resonance peaks, indicating excellent performance.
