Abstract
A laser diode chip has a laser facet, which includes a coating. The coating includes an inorganic layer and an organic layer. In one example, the coating has a number of inorganic layers, including a heat-conductive layer. For example, the inorganic layers may form a reflection-increasing or reflection-decreasing layer sequence.
