Abstract

The invention provides a drawing method of a photonic crystal fiber and the photonic crystal fiber, and the drawing method of the photonic crystal fiber comprises the steps: preparing a drawing material according to the structure of the photonic crystal fiber; preparing a preform rod based on the drawing material, and drawing the preform rod; preparing the air sleeve based on the drawing material, and drawing the air sleeve; sleeving the drawn prefabricated rod with the drawn air sleeve to obtain an initial photonic crystal fiber; and drawing the initial photonic crystal fiber to obtain the photonic crystal fiber. According to the invention, the prefabricated rod and the air sleeve are drawn in stages, and then the drawn prefabricated rod and the air sleeve are subjected to combined drawing, so that various process parameters in the drawing process can be accurately controlled, the stability and replaceability of PCF in the production process are improved, and meanwhile, under the conditions of stable temperature, air pressure and drawing speed, the production efficiency is improved. And the radial uniformity of the drawn PCF is better.

Description

【Technical field】 [0001] The invention relates to the technical field of optical fiber drawing, in particular to a drawing method of a photonic crystal optical fiber and a photonic crystal optical fiber drawn by the drawing method of the photonic crystal optical fiber. 【Background technique】 [0002] Photonic Crystal Fibers (PCFs) are also known as Micro-Structured Fibers (MSFs). The cores of PCFs are composed of solid glass rods or hollow glass tubes, and the cladding is composed of regularly distributed air holes. constitute. PCF has more superior characteristics than traditional fibers in the field of gain fibers. Specifically, the microporous structure of PCF introduces air, so that the equivalent refractive index of the cladding is smaller than that of the core. The adjustment of the spacing can precisely control the refractive index difference between the cladding and the core; PCF can realize the non-cut-off single-mode transmission characteristics based on a large m...
