Abstract

The invention provides a coupling method for suspended-core optical fibers. The coatings of the respective ends of a suspended-core optical fiber and a single-core optical fiber are stripped, the suspended-core optical fiber and the single-core optical fiber are washed and cut after stripping, so that the end surfaces of the optical fibers are smooth, an optical fiber welder is used for welding the stripped parts, the fusion points of the two sections of optical fibers are heated to carry out a fused biconical taper process, the optical power is monitored at the same time, the fused biconical taper process is stopped when the waist of the taper is thin enough so that the optical power-monitoring value reaches the predetermined coupling optical power, so that a tapered coupled section is formed, a quartz protective sleeve is sleeved on the tapered coupled section, and both ends of the quartz protective sleeve between the standard optical fiber and the suspended-core optical fiber are sealed. The invention has the advantages of simplicity, easy operation, low cost, stable optical performance, compact structure, high coupling optical power and on-line monitoring and convenient optical fiber integration and sensing application, and provides effective method and technique for directly embedded a suspended-core optical fiber device into a standard single-mode optical fiber communication link.

Description

technical field

[0001] The invention relates to the field of optical fiber technology, in particular to a method for coupling and connecting suspended core optical fibers and standard single-mode optical fibers or multi-mode optical fibers. Background technique

[0002] The main functions of optical connectors and optical couplers are to connect, synthesize, bifurcate, convert and attenuate optical signals or optical energy. Therefore, it is an indispensable and important device in optical fiber communication systems, optical fiber local area networks (including computer optical fiber networks, microwave optical fiber networks, optical fiber sensor networks, etc.) and various optical fiber sensor systems.

[0003] Optical fiber connection technology refers to combining the end faces of two optical fibers together. The basic requirement for the connection is to maximize the coupling of light energy from the input fiber to the receiving fiber. In addition to requiring small ...
