  • The authors show that exciton–polaritons—hybrid particles of light and matter—can be controlled in ways pure photons cannot, even when only a tiny amount of exciton character is present. In ultrathin WS2, indirect emission feeds the polaritons and enables condensation at room temperature.

  • Etch-free metasurfaces supporting bound states in the continuum have been used for lasing, although only as passive devices. Here, authors demonstrate highly coherent lasing from an active etch-free metasurface, showing a divergence angle of 0.2⁰, a linewidth of 0.04 nm and coherence time of 20.4 ps.

  • Miniaturized and efficient optical modulators are desired for data transmission, processing and communication. Here, the authors report the fabrication of exciton-polariton Mach–Zehnder modulators based on thin WS2 waveguides with a footprint of ~30 μm², modulation ratio up to −6.20 dB and nanosecond response times.

  • Exciton-polariton Bose-Einstein condensates in semiconductor microcavities are a unique manifestation of quantum coherence on a macroscopic scale. By examining the relationship between pumping intensity and polariton spectral properties, the authors demonstrate the cavity parameter space collapse and fundamental limit on the minimal power required for Bose-Einstein condensation.
