Semiconductor laser and method for producing a semiconductor laser

A semiconductor laser having a vertical emission direction comprising:

• a first active region and a first photonic crystal, wherein a first radiation emitted in the first active region during operation of the semiconductor laser is partially deflected in the vertical emission direction by the first photonic crystal;
• a second active region and a second photonic crystal, wherein a second radiation emitted in the second active region during operation of the semiconductor laser is partially deflected in the vertical emission direction by the second photonic crystal;
• and
• a connection region, which is arranged in the vertical emission direction between the first active region and the second active region and electrically conductively connects the first active region and the second active region to one another;
• wherein the first radiation propagates in a lateral direction in a first waveguide and the second radiation propagates in the lateral direction in a second waveguide.
