    A miniaturized optical frequency division system that could transfer the generation of microwaves, with superior spectral purity, to a complementary metal-oxide-semiconductor-compatible integrated photonic platform is demonstrated showing potential for large-volume, low-cost manufacturing for many applications.

    A triple phase transition, where changing a single parameter simultaneously gives rise to metal–insulator, topological and a parity–time symmetry-breaking phase transitions, is observed in non-Hermitian Floquet quasicrystals.

    A counter-intuitive state—known as a topological Anderson insulator—in which strong disorder leads to the formation of topologically protected rather than trivial states is realized in a photonic system.

    The response of a ternary, parity–time-symmetric system that exhibits a third-order exceptional point increases as a function of the cube-root of induced perturbations.

    An experimental realization of a photonic topological insulator is reported that consists of helical waveguides arranged in a honeycomb lattice; the helicity provides a symmetry-breaking effect, leading to optical states that are topologically protected against scattering by disorder.
