Abstract:
A VCSEL having a semiconductor body (1), which has a resonator volume, with a resonator axis, an active layer (8) that includes an active volume (9) that generates a radiation (7), and a first and second primary face, a first contact face (2) being formed on the first primary face and a second contact face (3) being formed on the second primary face, and in which the generated radiation (7) is decoupled at least in part through the first primary face,characterized in that the pump current (4) in a first region (12) is guided from the first primary face to the active layer (8), outside the resonator volume, predominantly parallel to the resonator axis; and that in a second region (13), the pump current (4) is carried to the active volume (9) predominantly perpendicular to the resonator axis, and an insulation layer (11) is embodied between the first region (12) and the resonator volume.
