Abstract: A method of manufacturing an optoelectronic component includes providing a carrier with an upper side; arranging an optoelectronic semiconductor chip above the upper side of the carrier; arranging a casting material over the upper side of the carrier, wherein the optoelectronic semiconductor chip is embedded in the casting material, and the casting material forms a cast surface; and removing a portion of the casting material at the cast surface, wherein a topography is generated at the cast surface, and the removal of a portion of the casting material at the cast surface takes place through laser interference structuring.
