Quantum dots
Letter by Ates et al.
Study on non-resonant dot–cavity coupling of individual quantum dots in micropillars under resonant excitation suggests a dominant role of phonon-mediated dephasing in dot–cavity coupling, revealing a pronounced effect over positive and negative quantum dot mode detunings.

Terahertz amplifier
Letter by Jukam et al.
Using an Auston switch to gain-switch a quantum cascade laser at ultrafast rate, high-field terahertz pulses that approach the laser saturation field can be obtained, benefiting terahertz imaging and sensing schemes.

Quantum optics
Letter by Nagali et al.
The first observation of the Hong–Ou–Mandel coalescence of photons with orbital angular momentum (OAM) is demonstrated and exploited for optimal quantum cloning of OAM-encoded qubits.

Terahertz optics
Article by Qin et al.
By modifying the properties of the guided modes of a wire laser through a wrenching dielectric or metallic structures that can be drawn away or close to the wire, scientists realize a terahertz wire laser with an unprecedented tuning range of ~137 GHz around frequency of ~3.8 THz.
