摘要：

A multicore fiber design with more than 10 coupled cores is investigated numerically and experimentally. It is revealed that a randomly coupled 12-core structure with a square lattice core arrangement can be realized within a 125 mu m cladding by employing fiber twisting of more than a few pi rad/m. A 125 mu m-clad twisting-rate-controlled 12-core fiber is then fabricated and a relative core density of 12 compared with conventional single-mode fiber is achieved while maintaining a low spatial mode dispersion characteristic of 8.4 ps/root km at 1550 nm. Finally, we experimentally evaluated the performance of 12 spatial channels by conducting a 24 x 24 MIMO transmission experiment.
