The microring resonator (#MRR) operates by the principle of evanescent field.

By what? 🤔

Sensors that operate by the principle of an #evanescent field utilizes the extension of the field inside the MRR into the surrounding. The range of this extension is in the order of the wavelengths of the radiation, ie in our case 1.5 micrometers. For #biodetection applications, target #biomolecules caused a variation of the refractive index in the surrounding and a shift in the resonance peak.
