Embodiment 1

[0043] Photonic crystal fiber sensors based on the surface plasmon resonance effect, such as Figure 1~2 As shown, the photonic crystal fiber is included, and the radial section of the photonic crystal fiber is provided with multiple annular arrays from the inside to the outside, and the annular array is formed by the arrangement of air holes. The base material between the air channels is silicon dioxide, the distance between adjacent air channels is 2.8 μm, and the radius of the air channels is 0.56 μm. An air hole in the second annular array from inside to outside is set as a sensing channel. The outer layer of the sensing channel is provided with a gold film, the inner wall of the sensing channel is provided with a temperature sensing layer, and the temperature sensing layer is supported by a quartz glass layer. The material of the temperature sensing layer is a mixture of ethanol and chloroform (7:3, v / v).

Abstract

The invention belongs to the technical field of electronic core industry, relates to manufacturing of sensitive elements and sensors, and relates to a photonic crystal fiber sensor based on a surface plasma resonance effect and application. Comprising a photonic crystal fiber, the radial section of the photonic crystal fiber is formed by arranging a plurality of hole channels in an array, one hole channel in the hole channel array is arranged as a sensing hole channel, a metal film is arranged on the outer wall of the sensing hole channel, a temperature sensitive layer is arranged on the inner wall of the sensing hole channel, and the sensing hole channel is of a hollow structure. The photonic crystal fiber sensor based on the surface plasma resonance effect has the advantages of being shorter in time delay, higher in sensitivity, smaller in nonlinear effect and the like.

Description

technical field [0001] The invention belongs to the technical field of electronic core industry, relates to the manufacture of sensitive elements and sensors, and relates to a photonic crystal fiber sensor based on surface plasmon resonance effect and its application. Background technique [0002] The information disclosed in this background section is only intended to increase the understanding of the general background of the present invention, and is not necessarily taken as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. [0003] According to the knowledge of the inventors, the air hole of the photonic crystal fiber is first provided with a gold film, and then filled with a heat-sensitive material (such as a mixed liquid of ethanol and chloroform), and the formed sensor has the characteristic of temperature sensing. However, after further research, it was found that this sensor has prob...
