Patent ID: 8525201

Claim:
A light emitting device comprising: a concave-convex pattern on a substrate, the concave-convex pattern including a plurality of grooves and a mesa between each of the plurality of grooves; a first reflective layer on a side surface of each of the plurality of grooves, the first reflective layer exposing a top surface of the mesa of the concave-convex pattern; an n-type clad layer on the concave-convex pattern, the n-type clad layer being in contact with the top surface of the mesa of the concave-convex pattern; an active layer on the n-type clad layer; a p-type clad layer on the active layer; a first electrode on a surface of the substrate, the first electrode facing the first reflective layer with the substrate therebetween; and a second electrode on a surface of the p-type clad layer.
