Laser diode chip having coated laser facet

A laser diode chip comprising:

• at least one laser facet having a coating;
• wherein the coating comprises inorganic layers and organic layers, the inorganic layers comprising a heat-conductive layer, the organic layers comprising a first organic diffusion barrier layer and a second organic diffusion barrier layer, and the organic layers further comprising a first organic layer;
• wherein the heat-conductive layer is arranged between the first organic diffusion barrier layer and the second organic diffusion barrier layer;
• wherein the heat-conductive layer comprises at least one of a transparent conductive oxide, indium tin oxide (ITO), zinc oxide (ZnO), gallium nitride (GaN), aluminum nitride (AlN), diamond-like carbon (DLC), silicon carbide (SiC), or graphene;
• and
• wherein the inorganic layers comprise a reflection-increasing layer sequence or reflection-decreasing layer sequence, and wherein the heat-conductive layer, the first organic diffusion barrier layer, and the second organic diffusion barrier layer are arranged between the reflection increasing layer sequence or reflection decreasing layer sequence and the first organic layer.
