Claim 12:
13. A light emitting diode (LED) chip, comprising:
an n-type layer;
a p-type layer; and
an active layer arranged between the n-type layer and the p-type layer, wherein the p-type layer, the active layer, and a portion of the n-type layer form an active LED structure mesa with at least one mesa sidewall;
wherein the at least one mesa sidewall forms a repeating pattern along the at least one mesa sidewall, the repeating pattern being formed by a plurality of features, wherein each feature of the plurality of features is an outwardly curved surface of the at least one mesa sidewall and each feature abuts at least one next-adjacent feature of the plurality of features at an intersection with the outwardly curved surface of the at least one next-adjacent feature.
