Optical spectra.
(a) Optical spectra of the comb. (b) Optical spectra of the ECL (blue line), part of the comb (green line) and the chosen 20 carriers (red line). (c) Optical spectra of the superchannel of back-to-back case (blue line), 400 km SSMF transmission case (black line) and the filtered signal (red line).
