Abstract

A metal silver-filled photonic crystal optical fiber that spontaneously generates SPR effect and a manufacturing method thereof belong to the field of optical fiber intelligent communication technology. The optical fiber includes a core and a cladding. The core is a solid quartz glass rod. The cladding includes quartz glass capillaries, air holes and silver wires. There are multiple layers of quartz glass capillaries arranged around the longitudinal direction of the fiber core. On the second layer Among the quartz glass capillary tubes, a silver wire is provided in the pore of one of the quartz glass capillary tubes. The manufacturing method is: designing the structure, arranging the structure and drawing the optical fiber. The obtained optical fiber can spontaneously produce the SPR effect. This method can produce photonic crystal fibers with different air hole structures and sizes that spontaneously produce the SPR effect without the need for subsequent coating or filling of the fiber. The resonance peak can be adjusted by adjusting the diameter of the air hole, the diameter of the filling silver wire, and the outer diameter of the capillary tube. The position is adjustable, the performance is good, and it also has the advantages of simple structure, convenient preparation, and adjustability, and can be used in the production of a variety of 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...
