Abstract
It is an object of the present invention to provide a multiple wavelength light source capable of generating lights of more wavelengths, and a generation method for multiple wavelength light using a multiple wavelength light source.A multiple wavelength light source of the present invention is a multiple wavelength light source having an optical comb generator for obtaining an input light and a group of lights shifted from the input light by predetermined frequencies; and an optical adjusting portion adjusting lights to be inputted to the optical comb generator; wherein the optical comb generator is composed of an optical fiber loop (105) which is provided with an optical SSB modulator (101), an optical amplifier (102) for compensating a conversion loss at the optical SSB modulator, an optical input port (103) for inputting lights from the light source, and an optical output port (104) for outputting lights, and the optical adjusting portion obtains a plurality of lights having different wavelengths.
