摘要
Abstract Owing to the rapid development of coherent optical fiber communication, free-space optical communication systems typically have a fiber-based coupling structure. In such systems, the received light field is coupled to a single-mode fiber or a few-mode fiber (FMF). In this study, we respectively establish an expectation model of FMF coupling efficiency under optical system aberration (OSA) and fiber positioning error (FPE) conditions, based on the Kolmogorov power-law spectrum and plane wave. The performance of the FMF with different coupling geometry parameters is analyzed. To the best of our knowledge, this is the first time the impacts of OSA and FPE on the coupling efficiency of a FMF under different turbulence strengths and coupling geometry parameters have been analyzed.
