Problems solved by technology

The chalcogenide glass used above contains the toxic component of As, and volatile gas is easy to be generated during heating and drawing, which will cause damage to the body. The reported chalcogenide glass optical fiber tapering method has poor controllability and low efficiency. The unique problems of optical fiber, such as low mechanical strength, easy fracture, and easy oxidation when heated, seriously restrict the preparation efficiency and quality of chalcogenide glass tapered optical fiber.

Abstract

The invention discloses a preparation method of a Ge-Sb-Se chalcogenide tapered fiber of different taper waists. The preparation method utilizes a specific and easy-to-operate tapering device to realize drawing of a Ge-Sb-Se chalcogenide tapered fiber, wherein during the tapering process, a first clamping plate and a second clamping plate of a clamp attached to each other under the magnetic force effect, and can compact the fiber through two soft rubber strips, so that the positioning effect of the fiber is good; and smooth operation of the tapering process can be guaranteed. Besides, as a stepping motor can control the tapering speed of the fiber and the heating area of a heating device is adjustable, the fiber areas with different lengths can be heated correspondingly and drawing of the Ge-Sb-Se chalcogenide tapered fiber of different taper waists can be realized; and as the temperature control accuracy of the heating device is 0.1DEG C and the three dimensional position of the heating device is adjusted by a three dimensional translation platform, the accuracy for heating the fiber can be improved. The preparation method of Ge-Sb-Se chalcogenide tapered fiber of different taper waists has the advantages of being simple in steps, being easy to operate, and being controllable in the external diameter of the taper area, wherein the diameter of the fiber core can be 700-2000Mum; the length of the taper area is 3-20mm; and the length of the taper area is greatly reduced relative to a traditional taped fiber.
