Abstract

The invention relates to a method for designing a single-sideband modulation electric control segmented sweep frequency source. The method is characterized in that output signals of the n DFB laser light sources are distributed at equal intervals according to the wavelength; output of the n DFB laser light sources is integrated and output at the same time through the wavelength division multiplexing technology, then frequency spectrum broadening is conducted on discrete output signals of the signals with the equal wavelength intervals through single side band modulation, and it is guaranteed that all frequencies are output in the broadening process so that swept-frequency signals with continuous wavelengths can be formed and output.
