Fiber Taper

Abstract

The invention discloses an optical fiber tapered rod, which includes a plurality of optical fiber filaments, which are gathered forward from the incident end and intersect, and the plurality of optical fiber filaments continue to extend forward in the form of spreading in the intersecting area to form an output end . The present invention gathers and crosses a plurality of optical fiber filaments forward from the incident end, so that the individual light rays of the optical fiber filaments with strong light and the optical fiber filaments with weak light can be mixed after crossing, so as to realize the homogenization of strong and weak light At the same time, the utilization rate of the light energy of the cone rod is improved, thereby improving the light coupling efficiency of the cone rod.

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.

[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
