Abstract

The invention discloses an optical biochemical sensor based on a slit waveguide structure, which is characterized by comprising an uploading end and a downloading end, wherein the uploading end and the downloading end are both straight slit waveguides; a first micro-ring waveguide arranged between the uploading end and the downloading end, wherein the first micro-ring waveguide is an annular slit waveguide; a second micro-ring waveguide connected with the first micro-ring waveguide in series, wherein the second micro-ring waveguide is arranged between the bottom of the first micro-ring waveguide and the downloading end, and the second micro-ring waveguide is an annular slit waveguide; wherein the radius of the first micro-ring waveguide is unequal to that of the second micro-ring waveguide, a first coupling distance is arranged between the uploading end and the top of the first micro-ring waveguide, and a second coupling distance is arranged between the bottom of the second micro-ring waveguide and the downloading end. A third coupling interval is arranged between the bottom of the first micro-ring waveguide and the top of the second micro-ring waveguide.

Description

technical field [0001] The present application relates to the field of photobiochemical sensing, in particular to an photobiochemical sensor based on a slit waveguide structure. Background technique [0002] Among various sensors, silicon-based optical sensors have the advantages of energy saving, environmental protection, miniaturization, easy integration, fast response speed, and anti-interference ability, which have covered many fields of biochemical sensors and become an important part of biochemical sensor devices. Silicon-based optical sensors have played a huge role in data collection in smart agricultural greenhouses, medical diagnosis and treatment, food safety, and air and water quality testing. [0003] Commonly used optical sensing elements are plasmonic waveguides, grating waveguides and microring resonators. Compared with the three, plasmonic waveguides have high sensitivity; grating sensors have a wide measurement range; microring resonators are small in size ...
