摘要:
An optoelectronic semiconductor body comprises a substrate (10), which has on a first main area (12) an epitaxial semiconductor layer sequence (20), suitable for generating electromagnetic radiation, in a first region (14) and a first trench (24) in a second region (22) adjacent to the first region (14), and at least one second trench (30) arranged outside the first region (14). The invention also relates to an optoelectronic semiconductor body and a method for producing an optoelectronic semiconductor body.

摘要:
In at least one embodiment of the light source (1), the latter includes at least one semiconductor laser (2), which is designed to emit a primary radiation (P) of a wavelength of between 360 nm and 485 nm inclusive. Furthermore, the light source (1) comprises at least one conversion medium (3), which is arranged downstream of the semiconductor laser (2) and is designed to convert at least part of the primary radiation (P) into secondary radiation (S) of a different, greater wavelength than the primary radiation (P). The radiation (R) emitted by the light source (1) here displays an optical coherence length which amounts to at most 50 μm.
