We study exciton-plasmon coupling in two-dimensional semiconductors coupled with Ag plasmonic lattices via angle-resolved reflectance spectroscopy and by solving the equations of motion (EOMs) a oscillator model accounting for all resonances system. Five are considered EOM model: semiconductor A B excitons, localized surface plasmon (LSPRs) nanostructures lattice diffraction modes array. investigated different 2D geometries, including monolayer MoS2 WS2 nanodisk bowtie arrays, examined dispersion lineshape evolution systems parameters. The approach provides unified description interaction weak, intermediate strong cases correctly explaining lineshapes complex This much deeper understanding light-matter interactions multilevel general will be useful to instruct design novel exciton-plasmonic devices variety optoelectronic applications precisely tailored responses.
