Abstract

The invention relates to an MIM (Metal-Insulator-Metal) waveguide structure based on a hybrid high-quality factor. The structure comprises a main body, wherein a light path is arranged above the mainbody; a first resonant cavity is arranged above the light path; and a first resonant ring is arranged in the first resonant cavity. The MIM waveguide structure based on the hybrid high-quality factorhas the advantages of small volume, easiness in integration and high sensitivity. A square ring is arranged in the main body, a round ring is arranged in the square ring so as to form different plasmon resonances, the hybrid plasmon resonance is formed, the type of the generated resonance is stable, so that the Q factor of the waveguide is improved, and therefore, the Q factor of the waveguide isstable.

Description

technical field [0001] The invention belongs to the technical field of waveguide structures, and in particular relates to a MIM waveguide structure based on a hybrid high quality factor. Background technique [0002] Based on the electromagnetic theory of light, guided wave optics studies the effects of propagation, scattering, polarization, and diffraction of light waves in optical waveguides, and has become the theoretical basis for various optical waveguide devices and fiber optic technologies. Usually people divide the research of optical fiber and other guided wave optics into two different fields, namely fiber optics and integrated optics, but their theoretical basis is the same, which is guided wave optics. [0003] A guided wave optical system generally consists of a light source, a coupler, an optical waveguide device, an optical modulator, and an optical detector. Compared with traditional, non-integrated discrete optical component systems, guided wave optical sys...
