  • Lasing and strong coupling can coexist in a single quantum dot coupled to a photonic-crystal-nanocavity mode. This provides important clues towards the realization of a single-quantum-dot nanolaser.

  • On-demand single-photon sources with high efficiency are required to realize many of the applications of quantum optics. By exploiting photonic mode transformation in a tapered nanowire, researchers have created a source that has an unprecedented extraction efficiency over an extremely broad spectral range.

  • A new woodpile-type photonic crystal nanocavity with a three-dimensional bandgap that supports lasing from embedded quantum dots paves the way for three-dimensional integrated photonic circuits and highly efficient nanolasers.

  • Understanding the photophysics of excitons in carbon nanotubes is important if they are to be fully exploited in optoelectronic devices. Sarpkaya et al. perform photoluminescence spectroscopy of nanotubes across an airbridge, finding a new narrow linewidth regime of intrinsic exciton behaviour.

  • Single-walled carbon nanotubes offer exciting optoelectronic applications but generally suffer from low quantum yields. Here, Luo et al. demonstrate that coupling nanotubes to plasmonic antennas can lead to large Purcell enhancement and corresponding increase in quantum yield as well as plasmonic thermometry at the single molecule level.

  • Ferromagnetism with a Curie temperature above room temperature in 2D materials is highly desirable for practical spintronics applications. Here, the authors demonstrate such phenomenon in monolayer MoS2 via in situ iron-doping and measured local magnetic field strength up to 0.5 ± 0.1 mT.
