Abstract

Disclosed are a metallic silver filled photonic crystal optical fiber capable of spontaneously generating SPR effect and a preparation method thereof, and belongs to the technical field of optical fiber intelligent communication. The optical fiber comprises a fiber core and a cladding, the fiber core is a solid quartz glass rod, the cladding comprises a quartz glass capillary tube, an air hole, and a silver wire, a multilayer quartz glass capillary tubes are arranged around the longitudinal direction of the fiber core, and a silver wire is arranged at the air hole of one quartz glass capillarytube in the second layer quartz glass capillary tube. The preparation method is as follows: according to the design structure, the arrangement structure, and the drawing optical fiber, the prepared optical fiber can spontaneously generate the SPR effect. The method can prepare the photonic crystal optical fiber capable of spontaneously generating SPR effect of different air hole structures and sizes, no need to subsequently coat or fill the optical fiber, and the resonance peak position can be adjusted by adjusting the diameter of the air hole, filling the diameter of the silver wire and theouter diameter of the capillary tube, the performance is good, meanwhile the method has the advantages of simple structure, convenience in preparation, adjustable adjustment and the like, and can be applied to the manufacturing of various optical components.

Description

technical field [0001] The invention belongs to the technical field of optical fiber intelligent communication, relates to the manufacture of optical fiber devices, in particular to a metallic silver-filled photonic crystal optical fiber with SPR effect spontaneously generated and a manufacturing method thereof. Background technique [0002] In 1996, after Knight, J.C. and others successfully drew the first refractive index-guided photonic crystal fiber, photonic crystal fiber entered the field of vision of many researchers, aroused great enthusiasm for research, and brought new technologies to the field of scientific research. direction of development. Compared with traditional optical fibers, the structural design of photonic crystal fibers is more flexible, and can produce many "singular" characteristics, such as unlimited single-mode transmission, low loss, controllable dispersion, nonlinear characteristics, high birefringence characteristics, etc. , so photonic crystal...
