The invention proposes a phase-shift electric-control sampling grating semiconductor laser. A DFB (distributed feed back) semiconductor laser consists of a first sampling grating area, a second sampling grating area and a phase-shift area, wherein gratings in the two sampling grating areas are sampling bragg gratings (SBG), the phase-shift area is positioned in the middle, and the sampling period is 1-10 micrometers; electrodes of the two sampling grating areas are connected together and are isolated from an electrode of the phase-shift area; the effective refractive index and the length of the sampling grating areas are expressed by nSBG and nP, and the effective refractive index and the length of the phase-shift area are expressed by LSBG and LP; and the primary control on the hot-shot wavelength of the laser can be realized only by changing the sampling period P, so as to form the phase-shift electric-control SBG DFB semiconductor laser.
