摘要 提出了一种改进环光纤结构,在原环光纤中引入一高折射率层,利用模式重组效应,增大了轨道角动量模式之间的有效折射率差,减弱了模式间的简并现象。通过数值仿真,对该改进环光纤结构的参数进行了优化设计,最终实现了不同轨道角动量模式间约10-3的有效折射率差,从而可以有效地抑制传输过程中的模间串扰,改善环光纤中轨道角动量模式的传输性能。 A modified ring fiber by introducing a high refractive index layer is proposed. With the effect of mode reorganization, index differences between the orbital angular momentum (OAM) modes are enlarged, thereby reducing the degeneracy among OAM modes. Parameters of the modified ring fiber are designed properly by numerical simulations, and modal index difference of about 10.3 is achieved, which effectively minimizes the coupling between OAM modes and thus improves the transmission property of ring fiber.
