| titleOfInvention | CO2 gas sensor with cascaded long-period waveguide grating structure and using method |
| abstract | The invention discloses a CO 2 gas sensor based on a cascaded long-period waveguide grating structure, comprising a silicon substrate, a waveguide lower cladding layer, a strip-shaped waveguide core layer and a waveguide upper cladding layer arranged in sequence from bottom to top. The upper surface of the waveguide core layer is provided with a first long-period waveguide grating and a second long-period waveguide grating, the strip-shaped waveguide core layer adopts polymer material, the waveguide lower cladding layer adopts polymer material, and the waveguide upper cladding layer adopts CO 2 gas selection Composite gas-sensing materials of polymers with strong adsorption and metal-organic framework materials. The invention also discloses a method for using the CO 2 gas sensor based on the cascaded long-period waveguide grating structure. The invention solves the problems of time-consuming ZIF-8 fabrication on the surface of the optical waveguide, high requirements for the uniformity of the ZIF-8 film and low sensor sensitivity, and at the same time utilizes the characteristic wavelength of the output spectral valley of the interferometer to be highly sensitive to the disturbance of the refractive index of the external environment Responsive to achieve highly sensitive and fast measurement of CO2 gas. |
