Problems solved by technology
[0003] like figure 1 As shown, in the current optical fiber taper, the positions of the entrance and exit of the optical fiber 1 are in one-to-one correspondence, so the direction of the light in each optical fiber travels independently. The first result of this method is, The cone rod cannot have the effect of uniform light, and at the same time, the utilization rate of the light energy of the cone rod is low, thereby reducing the optical coupling efficiency of the cone rod

Embodiment Construction
[0026] Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0027] In order to achieve the purpose of the present invention, as Figure 2-4 As shown, in some embodiments of the fiber optic cone rod of the present invention, it includes a plurality of optical fiber filaments 1, and the plurality of optical fiber filaments 1 gather forward from the incident end 2 and cross, and the plurality of optical fiber filaments 1 are in the crossing area Continue to extend forward to form exit ends 3 (only a few are shown in the figure, but they can be densely arranged as required). In this embodiment, multiple optical fiber filaments are gathered and crossed forward from the incident end, and the multiple optical fiber filaments continue to extend forward in the intersecting area to form an outgoing end. Using the characteristics of crossing, each optical fiber filament The entrance and exit are no longer in on...

The invention discloses an optical fiber taper rod, and the rod comprises a plurality of optical fibers, the optical fibers get together forward and intersect from an incident end, and the optical fibers continuously move forward in an intersecting area and in a dispersing way to extend and form a light emitting end. According to the invention , a plurality of optical fibers get together forward and intersect from the incident end, the light of the optical fibers with high light and the light of the optical fibers with low light can be mixed after the intersection, so that an uniform light effect of the high light and the low light is realized, the light energy utilization rate of the taper rod is improved, and the light coupling efficiency of the taper rod is improved.
Description
technical field [0001] The invention relates to an optical device, in particular to an optical fiber tapered rod. Background technique [0002] Optical fiber tapered rods have a very wide range of applications in the field of optoelectronics, such as figure 1 As shown, a plurality of optical fiber filaments 1 are gradually gathered together from the input end 2 to the output end 3 to form a tapered rod-like structure, which realizes the drawing effect on the optical fiber. [0003] Such as figure 1 As shown, in the current optical fiber taper, the positions of the entrance and exit of the optical fiber 1 are in one-to-one correspondence, so the direction of the light in each optical fiber travels independently. The first result of this method is that, The cone rod cannot have the effect of uniform light, and at the same time, the utilization rate of the light energy of the cone rod is low, thereby reducing the light coupling efficiency of the cone rod.
