Giacoumidis, Elias, Aldaya, Ivan, Jarajreh, Mutsam A., Tsokanos, Athanasios, Le, Son T., Farjady, Farsheed, Jaouën, Yves, Ellis, Andrew D. and Doran, Nick J. (2014). Volterra-based reconfigurable nonlinear equalizer for coherent OFDM. IEEE Photonics Technology Letters, 26 (14), pp. 1383-1386.


A reconfigurable nonlinear equalizer (RNLE) based on inverse Volterra series transfer function is proposed for dual-polarization (DP) and multiband coherent optical orthogonal frequency-division multiplexing (OFDM) signals. It is shown that the RNLE outperforms by 2 dB the linear equalization in a 260-Gb/s DP-OFDM system at 1500 km. The RNLE improves the tolerance to inter/intraband nonlinearities, being independent on polarization tributaries, modulation format, signal bit rate, subcarrier number, and distance.
