Optical Spectra.
(a) and (b) show the generated optical comb with 12.5-GHz carrier spacing before and after the band-pass filter; (c) shows the generated optical comb after modulation. The resolution of figure 4 (a), (b) and (c) is 0.02 nm. The power difference of each tone in the comb is less than 0.3 dB.
