1. A laser diode comprising:
a surface emitting semiconductor laser configured to emit electromagnetic radiation; and
an optical element arranged downstream of the semiconductor laser in a radiation direction,
wherein the optical element comprises a diffractive structure or a meta-optical structure or a lens structure,
wherein the optical element and the semiconductor laser are cohesively connected to each other,
wherein the semiconductor laser and the optical element are integrated with the laser diode,
wherein the semiconductor laser and the optical element are laterally enclosed by a cladding,
wherein the semiconductor laser and the optical element remain uncovered from the cladding in plan view, and
wherein the cladding is configured to reflect or absorb the electromagnetic radiation.
