The study aims to analyze the optical spectra of photonic structures containing WS2 excitons to enhance light–matter interaction.
Optical spectra analyzed using photonic structures made of hBN films with WS2 monolayers.
Structures enclosed within SiO2 layers and probed in attenuated total reflection configuration using Si prisms.
Different configurations tested, including those with stacked cells, to measure Rabi splitting.
Achieved Rabi splitting of 238.2meV between the lowest resonances in a structure of L=1050nm.
Found even larger splittings of 350.6meV and 382.2meV in thinner optimized structures of L=734nm and L=409nm, respectively.
Demonstrated three well-defined resonances resulting from strong exciton–guided mode coupling.

Valdés-Negrin et al. (2026) studied this question.
