Full presentation title: Experimental demonstration of utilizing adaptive optics to mitigate intra-modal-group power coupling of few-mode-fiber in a Two-channel 20-Gbit/s QPSK mode-division-multiplexed system.
We experimentally demonstrate utilizing adaptive optics to mitigate intra-modal-group power coupling in LP11 mode group for two-channel 20-Gbit/s QPSK mode-division-multiplexing transmission. Power penalty of < 2 dB and < 5 dB are achieved for the two channels respectively.
