Abstract

At present, the optical waveguide biochemical sensor that has been put into commercial use adopts a flat plate structure, and the evanescent field in the cover layer is used in the test process, and the test object is the effective refractive index in the cover layer. This kind of acceleration sensor has low optical coupling efficiency and poor lateral resonance resistance, which reduces its frequency response range and large signal distortion, and can not meet the high-frequency and high-precision seismic exploration. In this paper, a new multi-layer waveguide sensor is designed by using computer software technology to collect the information of objects through the network. It has stable performance, good lateral resonance resistance, high degree of integration and small volume, and can meet the requirements of high-frequency and high-precision seismic exploration. The nano-film on the surface of optical waveguide is characterized, and the advantages of porous sensitive film are verified compared with dense sensitive film. The influence of relative temperature on the sensor is studied. The higher the relative temperature, the more severe the influence. And can work reliably in the harsh flammable and explosive environment, which is expected to solve the assembly difficulties and long-term stability problems encountered by traditional optical fiber sensors in miniaturization and mass production.
