There is provided a multi-wavelength signal generation device capable of generating light having a plenty of wavelengths and a multi-wavelength light generation method using the multi-wavelength signal generation device. The multi-wavelength signal generation device includes a light comb generator for acquiring an input light and a light group shifted by a predetermined frequency from the input light, and a light adjusting unit for adjusting the light coming into the light comb generator. The light comb generator is formed by an optical fiber loop (105) having a light SSB modulator (101), a light amplifier (102) for compensating the conversion loss in the light SSB modulator, a light input port (103) via which the light from the light source is inputted, and a light output port (104) for outputting the light. The light adjusting unit includes a phase modulator, an intensity modulator or a frequency modulator.

L~invention concerne un dispositif de génération de signal multi-longueur d~onde pouvant générer de la lumière ayant de nombreuses longueurs d~onde, et méthode de génération de lumière multi-longueur d~onde utilisant le dispositif de génération de signal multi-longueur d~onde. Le dispositif de génération de signal multi-longueur d~onde comprend un générateur en peigne de lumière pour acquérir une lumière entrante et un groupe de lumières décalé d~une fréquence déterminée de la lumière entrante, et une unité de réglage de lumière pour régler la lumière parvenant dans le générateur en peigne de lumière. Le générateur en peigne de lumière est constitué par une boucle de fibre optique (105) possédant un modulateur de lumière SSB (101), un amplificateur de lumière (102) pour compenser la perte de conversion du modulateur de lumière SSB, un port d~entrée de lumière (103) au travers duquel la lumière de la source de lumière est introduite et un port de sortie de lumière (104) pour émettre la lumière. L~unité de réglage de lumière comprend un modulateur de phase, un modulateur d~intensité ou un modulateur de fréquence.
