Abstract
A conventional bi-fiber tri-directional fiber device needs a graded index lens and is high in cost. The bi-fiber tri-directional fiber device employs a cambered lens and is low in cost. The bi-fiber tri-directional fiber device comprises a lens, fibers and capillaries, the fibers are solidified in the capillaries, and end faces are polished. The bi-fiber tri-directional fiber device is characterized in that the lens has a curved surface plated with a light splitting film, so that a portion of light transmitted by a fiber penetrates through and the other portion is reflected into the other 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, adopt gradient-index lens, cost is high.
Innovation and creation content
Existing two fine three-dimensional optical fibre device, adopt gradient-index lens, cost is high.
The difference of the invention is to adopt toroidal lens, reduces cost.
Concrete scheme is: comprise lens, optical fiber, kapillary, and two optical fiber curings are inner at kapillary, and end face polishing, one is entered light, a bright dipping, lens end printing opacity.Lens end has a curved surface, and curved surface is coated with spectro-film, and light part transmission another part that optical fiber is transmitted reflects into another root optical fiber.The curved surface of lens can be sphere, and the center thickness of lens can be spherical radius, allow the plane of lens and fiber end face direct bonding time, these two faces all keep naked, do not need plated film.Can process this bonding plane becomes one to be less than the angle of 90 degree, to reduce noise with the optical fiber in kapillary.Lens directly can adopt packaged lens.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of first embodiment of the invention
Fig. 2 is the schematic diagram of second embodiment of the invention
