The invention relates to an optoelectronic device including a control circuit, a pixel comprising a photodetector, a light-emitting diode, and an intermediate region interposed between the photodetector and the light-emitting diode. The photodetector is sensitive to a detection wavelength λ. The light-emitting diode comprises an active stack with a cutoff wavelength Ac shorter than λand a buried electrode interposed between an interconnection stack of the circuit and the active stack, and covers a detection surface of the photodetector. The device furthermore comprises a via passing right through the active stack and extending as far as the interconnection stack; an electrical contact passing right through the active stack, in contact with the buried electrode; an electrical path electrically connecting the buried electrode to the control circuit and including the electrical through-contact and the via. The intermediate region is devoid of metal and the buried electrode is transparent to λ.
