Abstract
The utility model provides a double-fiber and three-directional optical fiber device. The existing double-fiber and three-directional optical fiber device needs a gradient-index lens and is high in cost. The double-fiber and three-directional optical fiber device is characterized in that a curved lens is adopted, and the cost is reduced. According to the specific scheme, the double-fiber and three-directional optical fiber device comprises a lens, optical fibers and a capillary tube, wherein the optical fibers are solidified in the capillary tube; and end surfaces of the optical fibers are polished. The lens is provided with the curved surface; a beam splitting film is plated on the curved surface, so that a part of light transmitted by one of the optical fibers is transmitted normally, but the other part of the light transmitted by the optical fiber is reflected into the other optical fiber.
Description
Technical field
The present invention relates to a kind of two fine three-dimensional optical fibre device, belong to fiber optic communication field.
Technical background
Existing two fine three-dimensional optical fibre device, adopts gradient-index lens, and cost is high.
Innovation and creation content
Existing two fine three-dimensional optical fibre device, adopts gradient-index lens, and cost is high.
The difference of the invention is to adopt toroidal lens, has reduced cost.
Concrete scheme is: comprise lens, optical fiber, kapillary, two optical fiber curings are in kapillary inside, end face polishing, and one is entered light, a bright dipping, lens end printing opacity.There is a curved surface lens end, is coated with spectro-film on curved surface, makes light part transmission another part that optical fiber transmits reflect into another root optical fiber.The curved surface of lens can be sphere, and the center thickness of lens can be spherical radius, makes the plane of lens and fiber end face direct when bonding, and these two faces all keep naked, do not need plated film.Can process this bonding plane and become an angle that is less than 90 degree with the optical fiber in kapillary, to reduce noise.Lens can directly adopt packaged lens.
