Abstract
A light emission device and method for producing the device. The device includes, on a substrate, a stack including an etching stop layer, a first barrier layer, an emitting layer, and a second barrier layer. The stop layer is of the same nature as the emitting layer. One may form a mirror on the stack, eliminate the substrate by etching, and form another mirror on the stop layer to obtain a micro-cavity. The device may be applied in particular to the detection of gas.
