Abstract

The invention discloses an atmosphere protection type chalcogenide glass optical fiber tapering device and a use method.The device comprises an optical platform, two electric displacement platforms, two optical fiber clamps, a seamed quartz tube and an atmosphere protection tube type resistance furnace.Firstly, the seamed quartz tube filled with a chalcogenide glass optical fiber penetrates through the atmosphere protection tube type resistance furnace and is clamped and fixed through a diaphragm; then the two ends of the optical fiber are fixed to the electric displacement platforms through the optical fiber clamps, inert gas is introduced into the furnace, the optical fiber is softened after being heated, and the electric displacement platforms are started for two-way traction tapering; finally ultraviolet curing glue is injected into the two ends of the seamed quartz tube for fixing the tapered optical fiber in situ.The device can taper the optical fiber under inert atmosphere protection, and oxidation of the surface of the optical fiber is effectively avoided; the temperature control effect on the periphery of the optical fiber is good, and the tapering success rate is high; in-situ fixing or packaging of the tapered optical fiber can be achieved; operation is simple, cost is low, and efficiency is high.

Description

technical field [0001] The invention relates to an optical fiber tapering device, in particular to an atmosphere-protected chalcogenide glass optical fiber tapering device and a use method. Background technique [0002] Chalcogenide glass tapered fiber (CGTF) has broad application prospects in biological / chemical sensing, nonlinear optics, micro-nano optics and other fields. For example, CGTF has excellent infrared transmittance and large evanescent field, so they are made into biological / chemical sensors for molecular detection and identification; CGTF has a very high third-order nonlinear coefficient, can be greatly adjusted group velocity dispersion, and it is easy to form extremely high light intensity in the optical fiber, so they are used in the field of infrared nonlinear optics, such as the generation of broadband infrared supercontinuum, the processing of optical signals, etc.; in addition, due to its large Due to the evanescent field and small volume, CGTF is ofte...
