摘要：

We designed a mode equalizer to handle mode-dependent loss (MDL) in mode division multiplexing systems. The proposed equalizer is based on a step-index long-period fiber grating (LPFG) and designed to attenuate the LP01 01 core mode while providing high transmission of the LP11 11 core mode. For a practical fiber design, we assumed a coating material with a higher refractive index than the cladding. Consequently, numerous leaky cladding modes should be analyzed. This study focuses on identifying the optimal core parameters to efficiently equalize MDL. (c) 2024 Optica Publishing Group
