Abstract
The present invention provide a laser, where the laser is divided into a laser region and a grating adjustment region through a first electrical isolation layer; the laser region is configured to generate optical signals, where the optical signals include an optical signal with a wavelength corresponding to a '0' signal and an optical signal with a wavelength corresponding to a '1' signal; the grating adjustment region is configured to adjust a wavelength of the grating adjustment region by controlling current of the grating adjustment region, so that the optical signal with the wavelength corresponding to the “1” signal of the laser region passes through the grating adjustment region, and the optical signal with the wavelength corresponding to the “0” signal of the laser region returns to the laser region, thereby implementing suppression to chirp of a directly modulated laser.
