This study focuses on the erbium doped nanostructured semi-conductors materials, innovativeand compatible with the Si technology to develop photonic devices such as waveguide, opticalamplifiers, and laser. The development of such devices is linked to the enhancement of the opticcommunications rate in the metropolitan network, but also to promote microelectronic and photonicfunctions on the same chips. Such applications are made possible due to the beneficial effects ofsilicon nanoclusters in erbium doped silica layer. After an excitation by a beam laser, the siliconnanocluster in its excited state transfers efficiently its energy to the surrounding erbium ions, for whichthe desexcitation is followed by the emission of photon at 1.54 μm.
