Abstract: In an embodiment a radiation-emitting laser diode includes a waveguide layer sequence having an active region configured to generate electromagnetic radiation with a preferred polarization direction, a first waveguide layer of a first doping type and a second waveguide layer of a second doping type, wherein the active region is arranged between the first waveguide layer and the second waveguide layer, wherein refractive indices of the waveguide layer sequence form a first effective refractive index for a transverse electric (TE) mode with its electric field oscillating in a first transverse direction and a second effective refractive index for a transverse magnetic (TM) mode with its electric field oscillating in a second transverse direction, and wherein an effective refractive index difference of the first effective refractive index and the second effective refractive index is at least 4·10−4.
