ABSTRACT:
A semiconductor laser chip comprises a semiconductor substrate, two laser stripes formed on the semiconductor substrate and each having a light waveguide path and a diffraction grating extending along the light waveguide path, and a groove for electrically isolating the laser stripes from each other. The facet phases of the diffraction grating at those facets of the plural laser stripes which are located at least in the same direction are different from each other. The diffraction gratings at the facets of two laser stripes comprise a plurality of grooves extending at an acute angle relative to the facets.
