Abstract
Herein presents a few-mode optical fiber, wherein the core comprising a main core() and 2N assistant cores(), wherein N is positive integer number. All the cores are formed by the same material and embedded in a low-index background (). The centers of the main core () and all the assistant cores () are located in a straight line. The assistant cores() are denoted based on the distance with the main core() as 1 , 2 , . . . N. The center-to-center distance between the main core () and the adjacent assistant core() is L=d+d. The center-to-center distance between the assistant core() and the adjacent assistant core() is L=d+dwherein i=1˜N−1 and ddenotes the diameter of assistant core() i. That is to say, the boundary of the main core () is tangent to the boundary of the adjacent assistant core(). Also the boundaries of the adjacent assistant cores() are tangent.
