Problems solved by technology

The performance problems of these materials have not been well resolved, which has limited the application of liquid core optical fibers in short wavelengths, especially in the ultraviolet band. The refractive index of the area is relatively high, accompanied by strong ultraviolet absorption, resulting in too small numerical aperture of the fiber, too large transmission loss, which is not suitable for transmitting light of ultraviolet wavelengths, and the liquid has a diffusion and penetration effect on the leather material, making the liquid core material The performance is degraded, and the optical fiber has low transmittance in the visible and near-ultraviolet spectral ranges, which limits the application of liquid core optical fiber

[0005] Such as figure 1 , the present invention is made by filling the clad hose 2 with multiple salt liquids 1 to form a flexible light guide, and the two ends are sealed with transparent light windows. The multi-salt liquid is composed of multiple aqueous phase addition solutions co-crystallized for 2-15 times. Solutions include: KCL 2 , CaBr 2 , CaCl 2 , NaH 2 PO 4 Wait. It has non-wetting plastic material and has good water absorption. The cladding hose can be composed of fluorine-containing and carbon-containing polymers, and the transparent light window can be a high-transmission quartz glass rod. Embodiment 1: Teflon tubes with an inner diameter of Φ5 and an outer diameter of Φ6 are used for the cortex, and the core material is poured into it. Among them, the core material is co-crystallized 8 to 12 times with multiple salt mixed aqueous solutions, and the contained components: CaCl 2 70%, CaBr 2 22%, KCL 2 4%, NaH 2 PO 4 4%. Both ends are sealed with h...

Abstract

This invention relates toa multisalf liquid core fiber characterizing in fully filled with multisalf liquid in a clad soft tube to form a flexible light conductor with sealed transparent light windows at both ends. Multisalt liquid is made up of multiple kinds of water-contained additive solution to be commonly crystallized for 2-15 times, containing KCL2, CaBr2, CaCl2, NaH2PO4 having high transmitting rate, large numerical aperture, broad light incidence angle, very high chemical stability and even higher boiling point and lower solidifying point in liquid core material.

Description

technical field [0001] The invention is a multi-salt liquid core optical fiber. It is mainly an optical fiber made of multiple salt solutions as the core material. Background technique [0002] Traditional liquid core optical fiber is generally made of alcohol solution or pure CaCl 2 It is the core material, which has wettability and non-absorbent property to the cladding material. The performance problems of these materials have not been well resolved, which has limited the application of liquid core optical fibers in short wavelengths, especially in the ultraviolet band. The refractive index of the area is relatively high, accompanied by strong ultraviolet absorption, resulting in too small numerical aperture of the fiber, too large transmission loss, and it is not suitable for transmitting light of ultraviolet wavelengths, and the liquid has a diffusion and penetration effect on the leather material, making the liquid core material The perform...
