Abstract :
We propose and experimentally demonstrate a new waveform reshaping technique to restore the orthogonality of the all-optical OFDM subchannels generated by an AWG-based MUX/DEMUX. The proposed scheme effectively restores the orthogonality and drastically improves the BER performance from 10-4 up to 10-6.
