70577-64 ABSTRACT OF THE DISCLOSURE An optoelectronic device, e.g. for integrated circuits, has an Si or III/V semiconductor layer and an insulating layer which is doped with lanthanides to generate an optical signal whose wavelength is determined by the 4f ions used. The insula- ting layer is preferably a fluoride which can be grown epit- axially on the semiconductor layer and the lanthanide element ion substituting for a metal ion of the material forming the insula- ting layer has the same valence as the metal for which it is substituted.
