Problems solved by technology

[0004] In the existing dispersion optical fiber, the scattering cladding is realized by polymer materials combined with inorganic scattering agents. Due to the low transmittance and poor heat resistance of polymer materials, the scattering effect is poor, and the stability and service life under high power Difference
On the other hand, since the waveguide structure is a step structure, the adjustment of the scattering loss is basically adjusted by the concentration of the dispersant in the scattering cladding, and the uniform dispersion and concentration o

Abstract

A quartz cladding large-power-transmission dispersion optical fiber and a manufacturing method thereof relate to the technical field of optical communication and related sensing devices. The dispersion optical fiber is composed of a core layer, a first quartz cladding and a second quartz cladding which are successively arranged from inside to outside. The core layer is doped with Ge element; the refractivity of the core layer changes in a gradual manner; and furthermore distribution power exponent is 1.5-3.3. The first quartz cladding contains bubbles and has a light scattering function. The refractivity of the second quartz cladding is higher than that of the first quartz cladding. The quartz cladding large-power-transmission dispersion optical fiber and the manufacturing method have advantages of enduring relatively high power and relatively high temperature, improving stability and reliability of the optical fiber, and effectively settling a color change problem of the optical fiber in illumination.

Description

technical field [0001] The invention relates to the technical field of optical communication and related sensor devices, in particular to a quartz-clad high-power transmission dispersion optical fiber and a manufacturing method thereof. Background technique [0002] Dispersion optical fiber, also known as linear optical fiber, side emitting optical fiber or whole body emitting optical fiber. When the incident light enters from the end face of the diffuse fiber, it can be emitted through the side surface of the entire fiber, thereby forming a whole-body luminescent fiber. Because it has such a unique luminous effect, it is often used in important scientific and technological fields such as medicine and environmental protection. [0003] Dispersion fiber generally consists of two parts: a fiber core with a high refractive index and an optical scattering cladding with a low refractive index. Generally, some dispersants are evenly mixed in the optical scattering cladding to de...
