Abstract

A simulation and analysis of a ring resonator-based sensor are presented. The ring resonator structure has two bus waveguides and two rings with a gap between the ring and the ring and bus waveguide. The radius of each ring is designed to be 3.1 μm. The ring resonator is designed such that both rings exhibit resonance at 1550 nm, and it is analyzed at mid-infrared wavelengths between 1500 and 1600 nm. The guided signal is launched through the bus waveguide to determine spectral properties, such as free spectral range and quality (Q-) factor. An improved Q-factor is observed in the simulation results for the optimized design. The improved Q-factor allows us to analyze the ring resonator for use in sensing applications.
