Abstract

The fiber includes central core area, cladding area and coating area. Cladding area includes buried micropore array in axial direction surrounding the core area and coating area. Changing shapes, structures, size and quantity and arrangement etc. forms major effective refractivity between two perpendicular directions in fiber so as to fabricate birefringence microstructure optical fiber. Fabricating method includes steps: preparing pure or doping quartz tiny stick and pure quartz tiny tube with certain wall thickness; fabricating the said sticks and tubes to specific shape; assembling the said sticks and tubes to desired shape; bundling sticks and tubes in quartz sleeve; fiber drawing forms optical fiber.

Description

technical field

[0001] The invention relates to a microstructure optical fiber and a manufacturing method thereof, in particular to a microstructure optical fiber with birefringence performance and a manufacturing method thereof. Background technique

[0002] Micro-structured optical fiber (MOF) refers to an optical fiber with a certain diameter and a certain number of microholes distributed in the cladding and (or) core of the fiber. The microholes are parallel to the central axis of the fiber and run through the entire fiber. When the arrangement of regular microholes on the cross-section of the fiber has a two-dimensional periodic structure and remains basically unchanged in the third dimension (the axis of the fiber), the refractive index of the cross-section of the fiber presents a two-dimensional periodic structure. The novel structural fiber with this characteristic is also called Photonic Crystal Fiber (Photonic Crystal Fiber).
