    We developed large-scale photonic-crystal surface-emitting lasers with controlled Hermitian and non-Hermitian couplings inside the photonic crystal and a pre-installed spatial distribution of the lattice constant, which leads to the realization of a continuous-wave brightness of 1 GW cm−2 sr−1.

    Because open-circuit voltage deficit is greater in wide-bandgap perovskite solar cells, the authors introduce diammonium molecules to modify perovskite surface states and achieve a more uniform spatial distribution of surface potential, enabling record voltage all-perovskite tandem solar cells.

    Magnetically tunable three-dimensional photonic crystals are used to achieve the experimental demonstration of Chern vectors and their topological surface states, showing the Chern vector to be an intrinsic bulk topological invariant in three-dimensional topological materials.

    Individually addressable ‘T centre’ photon-spin qubits are integrated in silicon photonic structures and their spin-dependent telecommunications-band optical transitions characterized, creating opportunities to construct silicon-integrated, telecommunications-band quantum information networks.

    Control loops generically produce braids of eigenfrequencies, and these braids form a non-Abelian group that reflects the non-trivial geometry of the space of degeneracies; these features are demonstrated experimentally using a cavity optomechanical system.

    Nonlinearity induced by a single photon is desirable because it can drive power consumption of optical devices to their fundamental quantum limit, and is demonstrated here at room temperature.

    In a tiny chip-based particle accelerator, phase-space control of the emerging electron beam demonstrates guiding over a length of nearly 80 micrometres and an indispensable prerequisite to electron acceleration to high energies.

    The insertion of an insulating layer into a multilayer light-emitting diode (LED) based on quantum dots and produced by depositing the layers from solution increases the performance of the LEDs to levels comparable to those of state-of-the-art organic LEDs produced by vacuum deposition, while retaining the advantages of solution processing.
