  • The authors report on the implementation of a photonic crystal waveguide with hyperbolic geometry supporting bound-in-the continuum exciton-polariton condensates. This unveils the coexistence of evanescent and ballistic polariton coupling behaviour with all-optical control.

  • Experimental evidence is presented for a new implementation of supersolidity in a driven-dissipative, non-equilibrium context realized in a photonic-crystal waveguide, demonstrating the breaking of translational symmetry with exceptionally low losses.

  • The authors have developed a custom-designed near-field probe to study the formation and emission characteristics of plexcitons arising from the interaction between surface plasmons in Au nanotrenches and excitons in monolayer WSe2.

  • 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.

  • Bound states in the continuum are topological states with useful symmetry protection properties. An experiment now shows how to use them to form macroscopically coherent complexes of polariton condensates.

  • Bound-states-in-the-continuum (BICs) display unique features like symmetry protection from dissipation, long lifetimes and topological charges. Here the authors demonstrate anisotropic Bogoliubov excitation spectrum of polariton condensate from a BIC using a patterned semiconductor GaAs/AlGaAs waveguide.
