Talk title:
SiGe Quantum dots as CMOS compatible, scalable quantum
optical sources in the telecom wavelength region?

Abstract:
The development of Si based, integrated quantum optical circuits has shown
tremendous progress in recent years. However, the generation of photonic
quantum states still relies on external lasers as sources for probabilistic
generation of single photons by non-linear processes like spontaneous four
wave mixing. On the other hand, III-V quantum dots have been shown to be
almost ideal  on-demand single photon sources. In my presentation I will show
some  recent results on our attempts to develop SiGe quantum dots into single
photon sources by increasing the radiative exciton recombination rate
employing photonic and defect engineering.
