LIGHT EMITTING DEVICE AND METHOD FOR MAKING SAME

摘要

The invention concerns a device comprising on a substrate (2) a stack including an etching boundary layer (6), a first barrier layer (10), an emitting layer (8) and a second barrier layer (12). The boundary layer is of the same type as the emitting layer. A mirror can be formed on the stack, the substrate eliminated by etching and another mirror formed on the boundary layer to obtain a micro-cavity. The invention is particularly applicable to gas detection.
