Manufacturing device of long conical optical fiber and using method thereof

Abstract

The invention provides a manufacturing device of a long conical optical fiber and a using method thereof, which solve the technical problem that the manufacturing of the conical optical fiber with the waist area length reaching several millimeters and high symmetry is difficult to realize in the prior art. Themanufacturing device comprises a base, a plurality of groups of electrode pairs are uniformly distributed side by side at intervals, and a linear guide rail is connected to the base; the optical fiber traction base is provided with a groove and a threaded hole, the groove is in sliding fit with the linear guide rail, a power output shaft of the rotating motor is coaxially connected with the lead screw, the lead screw is matched with the threaded hole, and the lead screw is parallel to the linear guide rail; the optical fiber traction base is provided with a rotating motor, a 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 and the power output shaft of the pair of rotating motors are coaxially arranged, and the center connecting line of the two electrodes of each electrode pair and the rod-shaped optical fiber are perpendicularly arranged in a crossed mode. The invention further discloses a using method of the manufacturing device of the long conical optical fiber, and the device can be widely applied to the technical field of manufacturing of conical 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...

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
