  • Effective use of single emitters in quantum photonics requires coherent emission, strong light-matter coupling, low losses and scalable fabrication. Here, Davanco et al. stride toward this goal by hybrid on-chip integration of Si3N4 waveguides and GaAs nanophotonic geometries with InAs quantum dots.

  • Atomically thin transition metal dichalcogenides constitute an ideal platform to investigate solid state excitonic effects. Here, the authors provide experimental evidence of a localized biexciton in a monolayer of WSe2, which induces an emission cascade of single photons.

  • Applications of ultra-low-loss photonic circuitry in quantum photonics, in particular including triggered single photon sources, are rare. Here, the authors show how InAs quantum dot single photon sources can be integrated onto wafer-scale, CMOS compatible ultra-low loss silicon nitride photonic circuits.

  • Using a controllably small and local optomechanical perturbation introduced by a focused lithium-ion beam it is now possible to map five modes of a silicon microdisk resonator (Q ≥ 20,000) with high spatial and spectral resolution.

  • Self-assembled quantum dots are good emitters, but lack emission control prior to device fabrication. Here a photoluminescence imaging technique to characterize position and emission properties of such quantum dots is demonstrated, enabling the realization of high-performance single-photon sources.
