Abstract
The invention discloses a thin fiber and a manufacture method of the thin fiber. The thin fiber comprises a diamond fiber core which comprises a strengthened fiber. A silica covering layer is arranged on the outer surface of the diamond fiber core. A coating layer is arranged on the outer surface of the silica covering layer. The diamond fiber core is a concrete or hollow fiber which is made of diamond. The manufacture method of the thin fiber includes the following steps. A fiber segment is arranged in a sealed container, pure methane gas and hydrogen are introduced into the sealed container. A radio frequency device or a microwave device is used for heating the gas in the sealed container so that an ionic state appears in the sealed container and lasts for at least five minutes until a diamond film or a diamond-like film is deposited on the surface of the fiber. A silica film is plated on the diamond film or the diamond-like film so as to obtain the thin fiber. The thin fiber has the advantages of being even in outer diameter, high in strength, simple in manufacture method, low in cost and good in application prospect.
Description
Technical field
The present invention relates to a kind of thin footpath optical fiber and manufacture method thereof.
Background technology
The job operation of existing thin footpath optical fiber mainly contains two kinds, all is based on existing ordinary optic fibre, and a kind of is that existing general silica optical fiber is heated and stretches, and forms thin footpath optical fiber; A kind of is with existing silica optical fiber acid corrosion, and as with hydrofluorite, the covering corrosion thinning of optical fiber being formed thin footpath optical fiber, the thin footpath optical fiber of two kinds of method mades all exists the inhomogeneous problem of external diameter, has limited its use.
Summary of the invention
The object of the invention is to overcome above-mentioned deficiency of the prior art, a kind of thin footpath optical fiber and manufacture method thereof are provided.Not only external diameter is even, intensity is high for this thin footpath optical fiber, and method for making is simple, cost is low, has application prospect preferably.
For achieving the above object, the technical solution used in the present invention is: a kind of thin footpath optical fiber, it is characterized in that: comprise the adamas fibre core, include reinforcing fibre in described adamas fibre core, the outside surface of described adamas fibre core is provided with the silicon dioxide covering, the outside surface of described silicon dioxide covering is provided with coat, the solid or hollow cored fibre of described adamas fibre core for being made of adamas.
