A long tapered optical fiber manufacturing device and using method thereof

Abstract

The invention provides a long tapered optical fiber manufacturing device and its use method, which solves the technical problem in the prior art that it is difficult to realize the manufacture of a tapered optical fiber with a waist length of several millimeters and high symmetry, which includes a base , multiple sets of electrode pairs are arranged side by side and evenly spaced, and the linear guide rail is connected to the base; the optical fiber traction seat is provided with grooves and threaded holes, and the grooves are slidingly adapted to the linear guide rails, and the power output shaft of the rotating motor is coaxially connected with the lead screw. The lead screw is adapted to the threaded hole, and the lead screw is parallel to the linear guide rail; the optical fiber traction seat is equipped with a rotating motor, and the power output shaft of the rotating motor is coaxially connected with the optical fiber clamp. After the rod-shaped optical fiber is straightened by the optical fiber clamp, the rod-shaped optical fiber, The power output shafts of a pair of rotating motors are coaxially arranged, and the center connection line of the two electrodes of each electrode pair and the rod-shaped optical fiber are arranged vertically and intersect each other. The invention also discloses a long tapered optical fiber manufacturing device The using method can be widely used in the technical field of manufacturing tapered optical fibers.

Description

technical field [0001] The invention relates to the technical field of manufacturing tapered optical fibers, in particular to a manufacturing device for long tapered optical fibers and a method for using the same. Background technique [0002] Optical fiber is a widely used optical device, which is widely used in sensing technology, communication and other fields. Due to the advantages of low cost, simple structure, and good sensing characteristics, tapered optical fibers can replace expensive optical fiber devices and achieve the same or even better results. The structure of its waist region (length, diameter) and cone region (length, profile) will cause it to have different optical properties. There are two types of tapered optical fibers in practical applications: one is to draw a section into a tapered light cone, the length is relatively short, and it is widely used in the coupling of optical fibers and optical fibers, light sources, and optical devices, as shown in th...

AI Technical Summary

Problems solved by technology

However, there are obvious deficiencies in the above-mentioned traditional methods for the manufacture of long tapered optical fibers. The disadvantages mainly include the low symmetry coefficient of the cone region, with a value of 0.9-0.5 or 1.7-3.7, and the length of the waist region is small, with a value of less than 2.5mm. Realize the manufacture of highly symmetrical tapered optical fibers with a waist length of several millimeters, which cannot meet the technical requirements of high-performance optical fiber sensors
