ABSTRACT:
A semiconductor laser has an antiresonant waveguide (10), which is formed by a layer sequence applied to a substrate (1). The layer sequence has outer waveguide regions (2, 8), reflection layers (3, 7), and a waveguide core (11) with an active layer (5). With this structure, semiconductor lasers with only slight vertical beam divergence and with a large beam cross section can be produced.
