Classification: CPC H | IPC H

Claim 14:
15. A laser device comprising:
a common waveguide layer; and
a plurality of laser bodies, wherein
the laser bodies each comprise an active zone configured to generate coherent electromagnetic radiation,
the laser bodies are arranged side by side on the common waveguide layer,
the laser bodies are directly adjacent to the common waveguide layer,
the laser bodies are phase-coupled to each other via the waveguide layer during operation of the laser device,

wherein the waveguide layer comprises a first sublayer, a second sublayer and an active region arranged therebetween, the active region being located in the coupling path of the waveguide layer,
the common waveguide comprising an active region, the active region being formed as an active quantum well layer of a Wannier-Stark modulator which, during operation of the laser device, brings about a change in a refractive index of the common waveguide layer as a result of an applied electric field.
