Abstract: An optoelectronic arrangement having a radiation conversion element and a method for producing a radiation conversion element are disclosed. In an embodiment, an optoelectronic arrangement includes a semiconductor chip having an active region configured to generate radiation, a radiation conversion element arranged downstream of the semiconductor chip in an emission direction and a reflective polarization element arranged downstream of the radiation conversion element in the emission direction. The radiation conversion element has a plurality of conversion elements, each of which has an axis of symmetry, the spatial orientation of the axes of symmetry has a preferred direction and a radiation emitted by the radiation conversion element has a preferred polarization. The reflective polarization element largely allows radiation with the preferred polarization to pass through and largely reflects radiation polarized perpendicularly to the preferred polarization.

Abstract: In one embodiment of the invention, the semiconductor laser (1) comprises a semiconductor layer sequence (2). The semiconductor layer sequence (2) contains an n-type region (23), a p-type region (21) and an active zone (22) lying between the two. A laser beam is produced in a resonator path (3). The resonator path (3) is aligned parallel to the active zone (22). In addition, the semiconductor laser (1) contains an electrical p-contact (41) and an electrical n-contact (43) each of which is located on the associated region (21, 23) of the semiconductor layer sequence (2) and is configured to input current directly into the associated region (21, 23). The n-contact (43) extends from the p-type region (21) through the active zone (22) and into the n-type region (23) and is located, when viewed from above, next to the resonator path (3).
