Abstract
The surface emitting laser device according to the embodiment includes a substrate, a first metal layer disposed on the substrate, a second metal layer disposed on the first metal layer, and a third metal layer disposed between the first metal layer and the second metal layer. The first to third metal layers may include different materials, and the second metal layer may include copper (Cu). The third metal layer may prevent diffusion of copper from the second metal layer into the first metal layer.
