Silicon has been considered for a long time unsuitable for photonic applications. Among the different approaches developed to overcome this problem, quantum confinement in silicon nanostructures and rare earth doping in crystalline silicon have received a great attention. A combination of these two approaches leads to a strong & efficient enhancement of the erbium emission in silicon nanocrystal. Luminescent emission wavelength (1.54um) of erbium corresponds to the minimum attenuation in long haul optical communication. Besides, Si-nc enables inexpensive and efficient pumping. Enhanced...
