Abstract: Light-emitting system comprising an integrated control photodetector and method for fabricating said system. This system is particularly suitable for optical connections and comprises a light-emitting electronic component (2) and a light guide (4) that receives the light emitted by the component, said guide comprising a light input face (8) arranged facing the component and reflecting a part of the light it receives, and a photodetector (14) integrated with the component and that detects a part of the light emitted by said component, wherein said photodetector is placed near to the component and is capable of receiving a part of the light reflected by the light input face. The active layer of the light-emitting electronic component is made of the same material as the active layer of the photodetector.

Abstract: The invention relates to a method for producing a multilayer on a receiving substrate, including the following steps: the formation of an initial substrate comprising a first material layer formed on the surface of a supporting substrate made of a second material, molecular adhesion bonding of the surface of the initial substrate comprising the first material layer to the bonding surface of a receiving substrate to obtain a bonded structure, partial removal of the initial substrate so as to leave a thin film of said second material on the first material layer, evaporation of the second material thin film with a selective stop on the first material layer, growth of at least one layer from the first material layer bonded to the receiving substrate, with the evaporation step and the growth step being carried out in the same technological apparatus.
