Optimisation of NbN thin films on GaAs substrates for in-situ single photon detection in structured photonic devices
Günther Reithmaier, Jörg Senf, Stefan Lichtmannecker +5
We prepare NbN thin films by DC magnetron sputtering on [100] GaAs substrates, optimise their quality and demonstrate their use for efficient single photon detection in the near-in…
Fluctuation induced luminescence sidebands in the emission spectra of resonantly driven quantum dots
Fabrice P. Laussy, Vase Jovanov, Elena del Valle +9
We describe how complex fluctuations of the local environment of an optically active quantum dot can leave rich fingerprints in its emission spectrum. A new feature, termed "Fluctu…
Broadband Purcell enhanced emission dynamics of quantum dots in linear photonic crystal waveguides
Arne Laucht, Thomas Günthner, Simon Pütz +8
The authors investigate the spontaneous emission dynamics of self-assembled InGaAs quantum dots embedded in GaAs photonic crystal waveguides. For an ensemble of dots coupled to gui…
