Abstract:
1. A method of processing an optical signal, comprising: inputting signal light into a first nonlinear optical medium to broaden a spectrum of the signal light through self phase modulation occurring in the first nonlinear optical medium, thereby obtaining first spectrally broadened light; compensating for chromatic dispersion effected on the first spectrally broadened light obtained in the inputting signal light, and maintaining a width of the spectrum of the signal light inputted in the compensating; and inputting the first spectrally broadened light processed by the compensating into a second nonlinear optical medium to broaden a spectrum of the first spectrally broadened light through self phase modulation occurring in the second nonlinear optical medium, thereby obtaining second spectrally broadened light; wherein a spectrum of the second spectrally broadened light is wider than the spectrum of the first spectrally broadened light.
