摘要： The phase modulation in which the frequency chirp becomes 0 at the timing which the user wants to synchronize, and the frequency chirp becomes larger as the time deviates in a positive or negative direction from this timing is applied to the signal light with each wavelength comprising pulse train of different timing. Thus, the optical pulses which deviate from the timing which the user wants to synchronize receive the frequency chirp in accordance with the amount of the timing deviation. The WDM signal light which has been chirped in this way is made to pass a linear dispersive medium, and the dispersion fit for the amount of frequency chirp is made to be given. By adjusting the amount of dispersion, it is possible to obtain the pulses which conform to the timing at which the user wants to synchronize the pulses of each wavelength.

摘要： An O/E conversion element converts an input NRZ optical signal into an electric signal. A clock recovery circuit recovers a clock signal from the electric signal obtained by the O/E conversion element. A phase modulator applies phase modulation to the NRZ optical signal, using the recovered clock signal. An intensity modulator applies intensity modulation to the NRZ optical signal, using the recovered clock signal. A dispersion medium compensates for a frequency chirp of an optical signal output from the intensity modulator.
