Single SiGe Quantum Dot Emission Deterministically Enhanced in a High-Q Photonic Crystal Resonator
Thanavorn Poempool, Johannes Aberl, Marco Clementi +9
We report the resonantly enhanced radiative emission from a single SiGe quantum dot (QD), which is deterministically embedded into a bichromatic photonic crystal resonator (PhCR) a…
Free-running Sn precipitates: an efficient phase separation mechanism for metastable GeSn epilayers
Heiko Groiss, Martin Glaser, Magdalena Schatzl +5
We report on the temperature stability of pseudomorphic GeSn films grown by molecular beam epitaxy on Ge(001) substrates. Both the growth temperature-dependence and the influence o…
Realization of high-Q/V bichromatic photonic crystal cavities defined by an effective Aubry-André-Harper potential
A. Simbula, M. Schatzl, L. Zagaglia +6
We report on the design, fabrication and optical characterization of bichromatic photonic crystal cavities in thin silicon membranes, with resonances around 1550 nm wavelength. The…
Local Density-of-States Mapping in Photonic Crystal Resonators by Deterministically Positioned Germanium Quantum Dots
Magdalena Schatzl, Florian Hackl, Martin Glaser +6
We report on mapping of the local density of states in L3 photonic crystal resonators (PCR) via deterministically positioned single Ge quantum dots (QDs). Perfect site-control of G…
