Example Embodiment
[0019] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings, but the implementation and protection of the present invention are not limited to this. It should be pointed out that if there are processes or symbols that are not specifically described in detail below, those skilled in the art can follow the current situation. There is technical understanding or realization.
[0020] This embodiment provides an anti-resonant toroidal fiber that supports multiple orbital angular momentum modes. The cross-section of the anti-resonant toroidal fiber for supporting multiple orbital angular momentum (OAM) transmission is as follows figure 1 Shown. The anti-resonant ring optical fiber includes: the fiber substrate 1 is made of a single quartz glass material, the ring core 2 is a ring silica glass tube, the cladding air holes 3 are arranged in a ring on the outer wall of the ring core 2, and the negative curvature...
