Claim Text:
1. An optical device comprising: a substrate; a graphite layer formed on the substrate; a semiconductor unit formed on the graphite layer; and an optical device layer comprising a first optical device layer and a second optical device layer formed on a surface of the semiconductor unit, a n-type semiconductor and an n-type semiconductor being alternatively formed with respect to the first layer and the second layer, wherein the optical device layer is formed to surround the semiconductor unit by stacking of the first optical device layer and the second optical device layer, and wherein if the semiconductor unit comprises a plurality of semiconductor units, the first optical device layer is formed either to surround each of the semiconductor units and the second optical device layer is formed as a thin film to cover the first optical device layer or the first optical device layer is formed as a thin film to cover each of the semiconductor units and the second optical device layer is formed as a thin film by stacking on the first optical device layer.
