摘要： A light emitting diode (LED) is provided. The LED at least includes a substrate, a saw-toothed multilayer, a first type semiconductor layer, an active emitting layer and a second type semiconductor layer. In the LED, the saw-tooth multilayer is formed opposite the active emitting layer below the first type semiconductor layer by an auto-cloning photonic crystal process. Due to the presence of the saw-tooth multilayer on the substrate of the LED, the scattered light form a back of the active emitting layer can be reused by reflecting and recycling through the saw-tooth multilayer. Thus, all light is focused to radiate forward so as to improve the light extraction efficiency of the LED. Moreover, the saw-tooth multilayer does not peel off or be cracked after any high temperature process because the saw-tooth multilayer has the performance of releasing thermal stress and reducing elastic deformation between it and the substrate.

摘要： A semiconductor laser device includes a substrate having a first surface and a second surface opposite to the first surface, an active region formed on the second surface of the substrate, a cladding layer formed on the active region, and an insulation region formed in the cladding layer to form on the second surface of the substrate a first laser region having a first size and a second laser region having a second size different from the first size. The first laser region is used for generating a first optical spectrum having a first laser mode channel space. The second laser region is used for generating a second optical spectrum having a second laser mode channel space. A combination of the first optical spectrum and the second optical spectrum forms a single mode laser. Without any gratings, the semiconductor laser device is easy to be fabricated and has a low fabrication cost.
