  High-brightness scalable continuous-wave single-mode photonic-crystal laser

  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.

  Interlayer exciton laser of extended spatial coherence in atomically thin heterostructures

  Efficient lasing from two transition-metal dichalcogenide layers is engineered by exploiting the excitonic states that emerge when the layers are placed together to form a heterostructure.

  Monolayer semiconductor nanocavity lasers with ultralow thresholds

  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.

  An electrically pumped polariton laser

  An electrically pumped polariton laser is constructed using a quantum well microcavity, and its polaritonic nature is demonstrated unambiguously by using a magnetic field to probe the part-light, part-matter character of the system.
