This paper describes the system performance of mode division multiplexing applications. The mode of amplification involved a ring profile-based multi-mode erbium-doped fiber amplifier with minimum support of 10 vortex spatial modes. The vortex modes are configured and generated by the vortex lens whose input is excited by a spatial laser source. The property of vortex modes can be processed with the linear combination of LP modes. The phase distribution of vortex modes has been twisted and the results achieved were spiral propagation in nature. Similar to the orbital angular momentum modes, the vortex mode is also part of the same group and offers minimal discrepancy among the higher-order modes. Following this approach, the proposed system promises efficient propagation of vortex modes at a higher data rate with minimum crosstalk and uniform gain distributions. The generated modes were classified as LP₀₁, LP₁₁, LP₂₁, LP₃₁, LP₄₁, LP₁₂, LP₁₃, LP₁₄, LP₀₂, LP₀₃ and their equivalent vortex modes were also investigated.

本文描述了模分复用应用的系统性能。放大模式涉及基于环形轮廓的多模掺铒光纤放大器，最少支持 10 个涡旋空间模式。涡流模式由涡流透镜配置和生成，其输入由空间激光源激发。涡流模式的性质可以用LP模式的线性组合来处理。涡流模式的相位分布已经扭曲，所获得的结果本质上是螺旋传播。与轨道角动量模式类似，涡旋模式也是同一组的一部分，并且在高阶模式之间提供最小的差异。按照这种方法，所提出的系统有望以更高的数据速率有效传播涡流模式，同时具有最小的串扰和均匀的增益分布。生成的模式被归类为 LP_{还研究了 01}、LP ₁₁、LP ₂₁、LP ₃₁、LP ₄₁、LP ₁₂、LP ₁₃、LP ₁₄、LP ₀₂、LP ₀₃及其等效涡流模式。
