A phase shift section is provided in a grating in one of the regions. In the semiconductor laser, .alpha. parameters for transverse electric (TE) and transverse magnetic (TM) polarization modes, in the vicinity of threshold currents for the TE mode and the TM mode, are made different from each other. An .alpha. parameter is defined by 4.pi./.lambda..multidot.(dn/dN)/(dg/dN) where .lambda. is a Bragg wavelength, n is an effective refractive index, N is an injection carrier density and g is a gain for each of the TE mode and the TM mode.
