Abstract

Using orbital angular momentum (OAM) modes can effectively enhance the information capacity of communication systems. To achieve high-performance OAM transmission characteristics in optical fiber waveguides, it is essential to minimally excite higher-order radial OAM modes in the optical fiber waveguide. Here, we propose two novel mechanisms to suppress the guidance of second-order radial OAM modes in the newly designed dual-core hollow-core fiber, while ensuring the support of a larger number of OAM modes. A detailed analysis process is also performed. The first method obtains the mode patterns and conducts a mathematical analysis based on the cutoff conditions for vector modes. The designed fiber structure…
