Experimental demonstration of orbital angular momentum (OAM) modes (De)multiplexing and transmission in 2-Km fiber with Nyquist 32-QAM coherent detection signals
We experimentally demonstrate orbital angular momentum (OAM) modes (de)multiplexing and transmission in 2-km few-mode fiber with 10-Gbaud Nyquist 32-QAM coherent detection signals without using MIMO. Favorable BER performance is achieved with low mode crosstalk < −25dB.
