Laser diode

A laser diode having a layer arrangement with layers arranged on one another, the layer arrangement comprising a first, a second and a third layer structure with at least one active zone and two waveguide layers, the active zone being arranged between the two waveguide layers, and having

• a first layer structure, the first layer structure extending along a Z axis in a longitudinal direction, along an X axis in a transverse direction and along a Y axis in a height direction, and
• a second and a third layer structure arranged along the Z axis on opposite longitudinal sides of the first layer structure and adjoining the first layer structure,
• wherein the active zone of the first layer structure is arranged offset in height relative to the active zones of the second and third layer structures,
• the active zone is arranged between a p contact and an n contact, an intermediate layer being arranged laterally with respect to the first layer structure in the second and third layer structures, the intermediate layer configured as an electrically blocking layer that hinders or prevents a current flow, and the intermediate layer being arranged between the active zone and the n contact, and
• the first layer structure comprises an intermediate layer, the intermediate layer of the first layer structure preventing a current flow, and the intermediate layer of the first layer structure is arranged offset in height relative to the intermediate layers of the second and third layer structures such that an electrically conductive connection is formed laterally between the second and third layer structures and the first layer structure so that an electrically conductive connection is formed between a p contact and an n contact via the active zone of the first layer structure.
