Abstract
A method for generating a high-frequency signal includes the steps of entering an optical pulse to a wavelength filtering device and generating modulating light having periodic wavelength intervals, and inputting the optical pulse outputted from the wavelength filtering device to a wavelength dispersive device to subject the optical pulse to treatment of different speeds according to the wavelength, and separating the optical pulse into time pulses independent with respect to the wavelength.
