Dynamics of soliton crystals in optical microresonators
A dissipative Kerr soliton crystal state is a temporally ordered regular ensemble of soliton pulses within a cavity. Chaotic driving of optical resonators enables the defect-free creation and dynamical characterization of these states.

Chip-integrated visible–telecom entangled photon pair source for quantum communication
Efficient photon pair sources connecting visible and telecommunication spectral regions are essential for viable long-distance fibre optic quantum communication architectures. A nanophotonic device is presented that allows kilometre-scale time–energy entanglement as an application.

High-dimensional one-way quantum processing implemented on d-level cluster states
The creation and manipulation of large quantum states is necessary for quantum information processing tasks. Three-level, four-partite cluster states have now been created in the time and frequency domain of two photons on-chip.

Stokes solitons in optical microcavities
Solitonic modes that are redshifted due to a Raman-related effect are reported in optical microcavities, and termed Stokes solitons.

Non-reciprocal Brillouin scattering induced transparency
By exploiting the interaction between light and phonons in a silica microsphere resonator it is possible to generate Brillouin scattering induced transparency, which is akin to electromagnetically induced transparency but for acoustic waves.

Playing pinball with light
Without a well-defined cavity, there is no obvious way to control the resonant modes in a random laser. Experiments now show that shaping the optical pump allows for controlled single-mode operation at predetermined lasing wavelengths.

Parity–time-symmetric whispering-gallery microcavities
It is now shown that coupled optical microcavities bear all the hallmarks of parity–time symmetry; that is, the system’s dynamics are unchanged by both time-reversal and mirror transformations. The resonant nature of microcavities results in unusual effects not seen in previous photonic analogues of parity–time-symmetric systems: for example, light travelling in one direction is resonantly enhanced but there are no resonance peaks going the other way.
