Compact triple Mach-Zehnder interferometer slot micro-ring resonator with ultra-high sensitivity and ultra-wide detection range for label-free sensing.

This paper proposes and analyzes a compact triple Mach-Zehnder interferometer slot micro-ring resonator (MZI-SMRR) with dimensions smaller than 50 µm × 50 µm, suitable for label-free detection sensing in various scenarios. The structure integrates th…
