Abstract
The invention discloses a method enhancing coupling performance of an optical device optical fiber inserting core and an optical fiber. The method comprises reducing hole diameter of the optical device optical fiber inserting core to a size which is obviously smaller than hole diameter of the optical fiber, enlarging transmitting power of a light emitter or improving coupling efficiency of the light emitter and the optical device optical fiber inserting core, accordingly enabling luminous power of coupling to the optical device optical fiber inserting core through the optical fiber or coupling to the optical fiber through the optical device optical fiber inserting core to meet a normal standard, and further solves the problem of large coupling result difference caused by the same hole diameter of the optical fiber inserting core and the optical fiber during four-direction plug-in. The method enhancing coupling performance of the optical device optical fiber inserting core and the optical fiber lowers aligning requirements of the optical device optical fiber inserting core and the optical fiber during coupling connection, achieves smoother coupling efficiency curve of the optical device optical fiber inserting core and the optical fiber, and improves torsion performance of coupling plug-in of the optical device optical fiber inserting core and the optical fiber.
Description
Technical field
The present invention relates to the optical device field, particularly a kind of method that strengthens optical device fiber stub and coupling fiber performance.
Background technology
When traditional optical device fiber stub is connected with Single-Mode Fiber Coupling, as shown in Figure 1, the aperture of the optical device fiber stub that adopts is the same with the aperture of single-mode fiber, generally be 8.3 μ m, because the fiber stub of optical device and the optical fiber alignment on can't realization theory when actual being of coupled connections, the coupling result difference when pegging graft test is very large in the four directions will to cause like this when Coupling power is tested fiber stub, reverse test and perform poor, the twisting property that optical device fiber stub and coupling fiber are pegged graft is relatively poor.
Summary of the invention
The object of the invention is to overcome existing above-mentioned deficiency in the prior art, a kind of method that strengthens optical device fiber stub and coupling fiber performance is provided.Described method is by reducing the pore size of existing optical device fiber stub, reduced the alignment requirement when the optical device fiber stub is connected with coupling fiber, reduced the coupling efficiency difference that the different directions coupling is pegged graft, realize more smooth optical device fiber stub and optical coupling efficiency curve, improved the twisting property that optical device fiber stub and coupling fiber are pegged graft.
In order to realize the foregoing invention purpose, the invention provides following technical scheme:
A kind of method that strengthens optical device fiber stub and coupling fiber performance is characterized in that comprising:
To be reduced to the aperture that is significantly less than optical fiber with the aperture of the optical device fiber stub of coupling fiber;
Increase the emissive power of optical transmitting set or improve the coupling efficiency of optical transmitting set and optical device fiber stub, so that reach arm's length standard by coupling fiber to the optical device fiber stub or by the luminous power that the optical device fiber stub is coupled to optical fiber.
Preferably, the aperture of described optical fiber is 8.3 μ m.
Preferably, the aperture of optical device fiber stub is reduced to is not more than 7 μ m.
Preferably, the aperture of optical device fiber stub is reduced to is not more than 6 μ m.
Preferably, the aperture of optical device fiber stub is reduced to is not more than 5 μ m.
Compared with prior art, beneficial effect of the present invention: reduced the alignment requirement when the optical device fiber stub is connected with coupling fiber, reduced the coupling efficiency difference that the different directions coupling is pegged graft, realize more smooth optical device fiber stub and optical coupling efficiency curve, improved the twisting property that coupling is pegged graft.

Fig. 3 is embodiment of the invention Y-direction pitch angle coupling measurement curve map.
Embodiment
The below will be clearly and completely described the technical scheme in the embodiment of the invention, and obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills belong to the scope of protection of the invention not making the every other embodiment that obtains under the creative work prerequisite.
According to the background technology introduction, the same 8.3 μ m that are with the aperture of single-mode fiber in aperture of the optical device fiber stub that adopts with tradition, the fiber stub of optical device and the optical fiber alignment on can't realization theory when actual being of coupled connections, thus coupling efficiency difference is large when causing the different directions coupling to peg graft, the grafting twisting property is relatively poor.
The embodiment of the invention will be reduced to the aperture that is significantly less than optical fiber with the aperture of the optical device fiber stub of coupling fiber, for example be reduced to respectively 7 μ m, 6 μ m, 5 μ m, because the aperture of having reduced fiber stub, coupling efficiency will decrease, at this moment by the emissive power that increases optical transmitting set or the coupling efficiency that improves optical transmitting set and optical device fiber stub, so that arrive the optical device fiber stub by coupling fiber, or reach arm's length standard by the luminous power that the optical device fiber stub is coupled to optical fiber, perhaps for some to the less demanding occasion of luminous power, coupling efficiency that this method is brought descends and can accept.
The concrete test result of the coupling efficiency of the embodiment of the invention such as Fig. 2, shown in Figure 3, Fig. 2 are embodiment of the invention Y-direction (laterally) skew coupling measurement curve map, and Fig. 3 is embodiment of the invention Y-direction (laterally) pitch angle coupling measurement curve map.Can find out from Fig. 2, Fig. 3, pass through the embodiment of the invention, when the aperture of optical device fiber stub is reduced to respectively 7 μ m, 6 μ m, 5 μ m by former 8.3 μ m, optical device fiber stub and the optical fiber coupling efficiency curve in the situation that Y-direction skew, Y-direction tilt is more smooth, that is to say when can obviously reduce the different directions coupling pegs graft because the inconsistent coupling efficiency difference of bringing of degree of registration improves the twisting property that optical device light core lock pin and coupling fiber are pegged graft.
