Embodiment Construction

[0016] The content of the present invention will be further described below in conjunction with the accompanying drawings and embodiments, but the present invention is not limited.

[0017] refer to figure 1 , the fiber fixing unit 1 includes a fiber fixing plate 3, the edge of the fiber fixing plate 3 is provided with a cylindrical adjustment shaft 4 connected with the fiber fixing plate 3, and the outside of the adjustment shaft 4 is covered with a damping rubber ring 5 , the adjustment shaft 4 covered with the damping rubber ring 5 is connected to the equipment casing part 6, the setting of the damping rubber ring 5 is to provide proper damping for the rotation process of the adjustment shaft 4, and keep it still when it stops at a certain position .

[0018] The two ends of the single-mode optical fiber 2 are linear, and the middle part is in the shape of a single ring or multiple rings in the same direction. The diameter of the single ring or the multi-turn rings in the ...

Abstract

The invention discloses a polarization controller, and the polarization controller is characterized in that the polarization controller comprises an optical fiber fixing unit, and a single-mode optical fiber which is connected with the optical fiber fixing unit, wherein the central part of the single-mode optical fiber is annular. Compared with a conventional polarization controller, the polarization controller can obtain a bigger polarization state change quantity under the same rotating angle. The polarization controller is simpler in structure, is small in structure size, can adjust the polarization direction of a polarization optical path more quickly, and is wide in application range.

Description

technical field [0001] The invention relates to the field of communication and sensing, in particular to transmission and testing of linearly polarized light, in particular to a polarization controller. Background technique [0002] In the traditional ring-shaped mechanical polarization controller, the ring-shaped optical fiber can only rotate around the straight part of the optical fiber that forms the "ring" during the working process. The disadvantage of this ring-shaped mechanical polarization controller is that it needs to control three ring-shaped optical fibers, the equipment is large in size, the control program is complicated, and it is difficult to achieve linear controllable changes due to the large number of variables. Contents of the invention [0003] The purpose of the present invention is to provide a polarization controller for the deficiencies of the prior art. Compared with the traditional polarization controller, this kind of polarization controller ca...
