摘要:
A laser light source for emitting coherent electromagnetic radiation has a vertical far-field radiation profile, having a series of semiconductor layers for generating the coherent electromagnetic radiation. An active region is located on a substrate. The coherent electromagnetic radiation is emitted during operation in an emission direction at least from a main emission region of a radiation output surface and the radiation output surface is formed by a side surface of the sequence of semiconductor layers. A filter element suppresses coherent electromagnetic radiation in the vertical far-field radiation profile. The radiation was generated during operation and emitted by an auxiliary emission region of the radiation output surface. The auxiliary emission region is vertically offset from and spatially separated from the main emission region.

A composite substrate (1) comprising a substrate body (2) and a utility layer (31) fixed on the substrate body (2). A planarization layer (4) is arranged between the utility layer (31) and the substrate body (2). A method for producing a composite substrate (1) applies a planarization layer (4) on a provided utility substrate (3). The utility substrate (3) is fixed on a substrate body (2) for the composite substrate (1). The utility substrate (3) is subsequently separated, wherein a utility layer (31) of the utility substrate (3) remains for the composite substrate (1) on the substrate body (2).
