    An experimental design consisting of a photonic-crystal nanoslab covered with upconversion nanoparticles demonstrates the phenomenon of supercritical coupling, resulting in giant enhancement of upconversion by photonic bound states in the continuum.

    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.

    By introducing a further modal dimension to transform a two-dimensional photonic waveguide array, a photonic topological insulator with protected topological surface states in three dimensions, enabled by a screw dislocation, is demonstrated.

    A spatially oscillating two-dimensional waveguide array is used to realize a photonic topological insulator in synthetic dimensions with modal-space edge states, unidirectionality and robust topological protection.

    The incorporation of large numbers of chemically diverse functional components into microfabricated structures at precise locations is challenging; now the precision placement of DNA origami by directed self-assembly is shown to overcome this problem for the purpose of reliably and controllably coupling molecular emitters to photonic crystal cavities.

    Chiral nematic liquid crystals are self-organized helical superstructures in which the helices can stand or lie, and lie in either a uniform or a random way; here, the helices are reversibly driven from a standing arrangement to a uniform lying arrangement and then rotated in-plane—solely by light.

    Exceptional points are singularities in non-Hermitian systems that can produce unusual effects, and it is shown that a Dirac cone in a photonic crystal can generate a continuous ring of exceptional points through flattening the tip of the cone.

    A miniature laser is reported that uses two-dimensional tungsten diselenide as the active medium, which is placed on a photonic crystal membrane that acts as the laser cavity; the laser emits visible light, with an ultralow pump threshold.

    Theoretical and experimental studies reveal that light can be confined within a planar dielectric photonic crystal slab even though the frequency of this optical bound state is inside the continuous spectrum of extended states from the same symmetry group.
