| 摘要 |
A light emitting device having auto-cloning photonic crystal structures comprises a substrate, a first semiconductor layer, an active emitting layer, a second semiconductor layer and a saw-toothed multilayer film comprising auto-cloning photonic crystal structures. The saw-toothed multilayer film provides a high reflection interface and a diffraction mechanism to prevent total internal reflection and enhance light extraction efficiency. The manufacturing method of the light emitting device having auto-cloning photonic crystal structures is presented here.
