ABSTRACT:
A semiconductor laser with a semiconductor substrate, a laser layer arranged on the semiconductor substrate, a waveguide arranged parallel to the laser layer and a strip shaped grating structure is disclosed. The laser layer, the waveguide and the grating are arranged a configuration which results in weak coupling between the laser light and the grating structure, so that the laser light interacts with an increased number of grating elements. A process for the production of such a semiconductor laser is also disclosed.
