In this work, we propose a novel scheme that introduces mode-group granularity, termed cyclic mode-group permutation (CMGP). Figure 2(b) explains the CMGP ...

Jan 1, 2024 · This talk discusses how a mode-group permutation scheme is used to reduce the impact of modal dispersion and allow transmission of 15×184×24.5 ...

We investigate the transmission distance of a 20-Gbaud 6-mode dual-polarization QPSK transmission system using the Kramers–Kronig(KK) receiver based on the ...

Dec 10, 2024 · In this method, the 15 spatial modes undergo a cyclic shift, moving one position towards higher-order modes at each permutation stage. The ...
