Abstract: A galvanic optocoupler structure (10) of the type comprising at least one optical source (3) coupled to an optical detector (5) and separated therefrom by a transmission means (4) of an optical signal is described. Advantageously, the optical source (3) is realised by means of an organic LED comprising a optical substrate (4) transparent with respect to the optical signal and associated directly with the optical detector (5) to serve as transmission and insulation means (4) between the optical source (3) and the optical detector (5).
The hybrid integration process of such a galvanic optocoupler structure is also described.
