Description
Technical field
The present invention relates to a kind of silica fibre and preparation method thereof, particularly a kind of high-performance anti-radiation quartz optical fiber and combined method method for making thereof belong to the optical fiber technology field.
Background technology
Can optical fiber is applied to radiation association areas, particularly optical fiber such as Aero-Space, nuclear industry, military affairs more and more widely proper communication under radiation environment, particularly important to military affairs.And conventional fibre core germanium-doped silica fiber, because loss obviously increases under radiation regimes, as 3 * 10
3Under Gy, 3.5 hours the radiation gamma, single-mode fiber has the radioinduction loss of 30dB/km approximately, so, be not suitable for the application in these fields.For this reason, development radioresistance optical fiber becomes international research and hot of research and development.
Radioresistance optical fiber is meant can be resisted because the optical fiber of atomic radiation, gamma-rays, X ray, the transmission performance that the produces decline of ultraviolet ray irradiation institute.It is the colour center that produces in silica fibre owing to radiation that radiation makes the Optical Fiber Transmission ability drop, promptly due to the atom defect.These colour centers are mainly relevant with the initial atom defect of contained doping quality and optical fiber itself in the optical fiber.The part free electron that the former can make radiation produce is captured by some the painted positive ions (as Fe, Ni, Pb etc.) in the optical fiber, reduces and form new colour center, and these colour centers reduce the Optical Fiber Transmission ability; And the latter to be high-octane radiating particle cut off has the ≡ Si-O-Si ≡ key of initial atom defect, thereby formed E ' colour center and the hollow colour center of non-bridged bond oxygen.Wherein, the colour center of preceding a kind of factor generation can be solved by adopting highly purified quartz; A kind of factor in back is how to reduce initial atom defect, makes optical fiber produce few scission of link colour center under radiation condition.
At above these science and technology of preparing problem, abroad be engaged in the research work of radioresistance optical fiber till now from the eighties always, main work performance is in the following aspects: (1) adds a certain amount of OH in pure silica fibre core
-, as 600-800ppm, can improve gamma-rays, the deep UV (ultraviolet light) of optical fiber, the capability of resistance to radiation of X-ray, but because OH
-Adding, can strengthen in its loss of near infrared communication wave band, influence proper communication.In addition, OH
-Implantation concentration also be limited, when to a certain degree will be saturated.(2) the low OH of adding 5-10ppm in the silica core material
-, and the fluorine of doping 200ppm can improve the capability of resistance to radiation of optical fiber, this optical fiber is the transmission that is applicable to vacuum and deep UV (ultraviolet light), but also can be than the germnium doped core fibre loss height of routine at the near infrared communication wave band.(3) Russian Doanov has studied a kind of radioresistance optical fiber of fibre core nitrating, and at the 1300nm-1600nm wave band, 2 hours postradiation measurement induction losses of 10Gy gamma-rays are than the slightly high 0.5-1.0dB/km of pure silica fibre.(4) pure silica core is mixed the optical fiber of fluorine covering, and this single-mode fiber is 3 * 10
3Under Gy, 3.5 hours the radiation gamma, the radioinduction loss is about 10dB/km, and for the optical fiber communication of long distance, this value is operable.
