| titleOfInvention | Refractive index sensing device based on few-mode silicon nitride micro-ring resonator |
| abstract | A refractive index sensing device based on a few-mode silicon nitride micro-ring resonator comprises a plurality of waveguide units which are arranged in parallel, each unit is composed of a single-mode straight waveguide for input and output and a single few-mode annular waveguide for resonance, the straight waveguides and the annular waveguides in the units are arranged on the same plane and are not in contact, the straight waveguides among the units are parallel, and two ends of the single-mode straight waveguide are respectively used as an input end and an output end. At least one mode is supported by a single straight waveguide and a single annular waveguide structure of the all-pass micro-ring resonator, so that resonance peaks corresponding to a basic mode and a high-order mode can be generated in a transmission spectrum, and the drift of optical fields of different modes to the change of the refractive index is different, so that the refractive index sensing measurement can be performed by utilizing the characteristic. |
