| Outline of Final Research Achievements |
We numerically and experimentally investigated the performance of the weakly-coupled mode-multiplexed technique, which is possible to reduce drastically the computational complexity of the MIMO signal processing. We implemented an optical MIMO receiver based on a FPGA board, a mode demultiplexer, and two optical coherent receivers. With the MIMO receiver, we experimentally demonstrated real-time weakly-coupled 10-mode fiber transmission of wavelength-multiplexed 10-mode-multiplexed dual-polarization QPSK optical signals. The results suggest that weakly-coupled mode-multiplexed technique make possible to increase the transmission capacity in proportional to the mode-multiplexed number, and the weakly-coupled mode-multiplexed technique is effective to enhance the transmission capacity of the optical fiber transmission systems.
