A tunable laser (300, 1100) includes a gain module (301, 1101), a sinusoidal comb filter (302, 1103), a narrowband comb filter (303, 1102), a wavelength configuration circuit (304, 1105), and a wavelength tuning circuit (305, 1104). The sinusoidal comb filters (302, 1103) have band-pass filter windows spaced apart from each other, and the narrowband comb filters (303, 1102) have band-pass filter windows spaced apart from each other. The wavelength configuration circuits (304, 1105) are used to receive the wavelength information, set the position of the first band according to the wavelength information, and the wavelength tuning circuits (305, 1104) are used to tune the band-pass filter window of the narrowband comb filters (303, 1102), so that the first band and the second band overlap. The tunable lasers (300, 1100) can quickly tune the laser.
