Disclosed are a light emitting diode (LED) having a photonic crystal structure and a method of fabricating the same. An LED comprises a support substrate, a lower semiconductor layer positioned on the support substrate, an upper semiconductor layer positioned over the lower semiconductor layer, an active region positioned between the lower and upper semiconductor layers, and a photonic crystal structure embedded in the lower semiconductor layer. The photonic crystal structure may prevent the loss of the light advancing toward the support substrate and improve the light extraction efficiency. |
