Abstract

An LED device comprises a mesa comprising semiconductor layers, the semiconductor layers including an N-type layer, an active layer, and a P-type layer, the mesa having a top surface and at least one side wall, the at least one side wall defining a trench have a bottom surface. A transparent conductive layer is on at least one side wall and in the trench. A cathode layer is in the trench on the transparent conductive layer. A p-type contact is on the top surface of the mesa. In some embodiments, a spacer layer is formed between the transparent conductive layer and the cathode layer. In other embodiments, a distributed Bragg reflector is formed between the transparent conductive layer and the cathode layer.
