Light emission from erbium-doped nanostructures embedded in silicon microcavities

We present the findings of high-efficient Er3+-related View the MathML source absorption and emission from self-assembled quantum wells (SQW) embedded in silicon microcavities. The microcavities are prepared by the short-time diffusion of boron into the Si(100) wafer doped with erbium. The intraband electron transitions accompanied by tunneling through strongly coupled SQW series are observed to excite the View the MathML source-intracenter emission, View the MathML source, that is enhanced by strong sp–f mixing in the range of the Rabi splitting revealed by the transmission spectra.
