Abstract: In an embodiment a beam-guiding cavity structure includes at least one first curved surface, one second curved surface and one third curved surface spanning a cavity, the first-third curved surfaces respectively having at least one first focal point and one second focal point, wherein the cavity is configured such that substantially no distance is laterally formed between the first focal point of the first curved surface and the second focal point of the second curved surface, wherein the cavity is further configured such that substantially no distance is laterally formed between the first focal point of the second curved surface and the second focal point of the third curved surface, wherein the first focal point of the second curved surface is arranged next to a connecting line of the first and second focal points of the first curved surface, wherein the first focal point of the third curved surface is arranged next to a connecting line of the first and second focal points of the second curved surface, and wherein the first, second and third curved surfaces have different shapes or dimensions to one another.
