Strong coupling of excitons in monolayer ${\mathrm{WS}}_{2}$ with Brillouin zone folding induced quasibound states in the continuum (opens in new tab)

Author(s): Xiongwei Guo, Yingying Zhang, Jinhai Si, Xun Hou, and Kuidong WangAll-dielectric optical metasurfaces that supporting optical quasibound states in the continuum (QBICs) offer a promising platform in realization of strong light-matter coupling with monolayer transition-metal dichalcogenides (TMDCs). Such coupled systems are critical for wide range of applications i…[Phys. Rev. B 113, 235425] Published Thu Jun 18, 2026
