Abstract

The invention relates to an optical fiber probe, in particular to a bisymmetrical PCF-SPR probe working in a high-refractive-index solution environment. A central air hole is arranged in the cladding of a photonic crystal fiber, and a central air hole is arranged around the central air hole. Eight small air holes in the outer layer and large air holes in the outer layer are arranged in a regular octagonal cross arrangement, and the outer wall of the cladding is coated with a silver-graphene composite film. When light is injected into the two photonic crystal fibers, the light of different wavelengths propagates along the axial direction in the fiber in a specific mode, and the surface plasmon wave is recombined in the silver-graphene in a fixed mode. Intramembrane spread. When the light of a certain wavelength in the fiber has the same wave vector as the surface plasmon wave in the silver-graphene composite film, energy coupling occurs in the silver-graphene composite film, and the light energy in the fiber is coupled back to the silver-graphene composite film. In the olefin composite film, the light energy in the optical fiber is reduced. The wavelength of light corresponding to the maximum energy loss is the resonance wavelength.

Description

Technical field: [0001] The invention relates to an optical fiber probe, in particular to a double symmetrical PCF-SPR probe working in a high refractive index solution environment. Background technique: [0002] Surface Plasmon Resonance (SPR) is a relatively special physical optics phenomenon, and it is also an optical sensing technology used to detect changes in the refractive index of a medium. Because surface plasmon resonance sensing technology has outstanding advantages such as no need for marking, real-time detection, strong anti-interference ability, high sensitivity, and simple structure, it has broad prospects in many fields such as biology, medical treatment, environmental protection, and energy. [0003] Compared with the well-known traditional optical fiber, Photonic Crystal Fiber (PCF) contains small air holes arranged in different modes and periodically in order to make its internal refractive index distribution more flexible. . In recent years, photonic cr...
