PURPOSE: A single wavelength single mode laser array and a fabrication method thereof are provided which can fabricate a multiwavelength array light source easily and economically using a sampling grating(SG). CONSTITUTION: An asymmetric sampling grating laser is arranged on a substrate(11) with a fixed gap. The asymmetric sampling grating laser includes an active region(21) divided into two regions(A,B), and asymmetric sampling gratings(12a,12b) distributed on a bottom of the active region with different period each other. And an effective refractive index variation layer(22) is arranged on one side of the active region and has different Bragg wavelength on two regions of the active region respectively.
