An optoelectronic semiconductor chip and a method for manufacturing a semiconductor chip are disclosed. In an embodiment an optoelectronic semiconductor chip includes a plurality of fins and a current expansion layer for common contacting of at least some of the fins, wherein each fin includes two side surfaces arranged opposite one another and an active region arranged on each of the side surfaces, wherein the plurality of fins include inner fins and outer fins having an adjacent fin only on one side, and wherein the current expansion layer is in direct contact with the inner fins on their outside.

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.
