    • A light-emitting device and the method for making the same is disclosed. The light-emitting device is a semiconductor device, comprising a growth substrate, an n-type semiconductor layer, a quantum well active layer and a p-type semiconductor layer. It combines the holographic and the quantum well interdiffusion (QWI) to form a photonic crystal light-emitting device having a dielectric constant of two-dimensional periodic variation or a material composition of two-dimensional periodic variation in the quantum well active layer. The photonic crystal light-emitting devices can enhance the internal efficiency and light extraction efficiency.
