## Description

- description: Various exciton species in transition metal dichalcogenides (TMDs),
    such as neutral excitons, trions (charged excitons), dark excitons, and biexcitons,
    have been individually discovered with distinct light-matter interactions. In
    terms of valley-spin locked band structures and electron-hole configurations,
    these exciton species demonstrate flexible control of emission light with degrees
    of freedoms (DOFs) such as intensity, polarization, frequency and dynamics. However,
    it remains elusive to fully manipulate different exciton species on demand for
    practical applications. Here, we investigate the contrasting light-matter interactions
    to control multiple DOFs of emission light in a hybrid monolayer WSe2-Ag nanowire
    (NW) structure by taking advantages of various exciton species. These excitons,
    including trions, dark excitons and biexcitons, are found to couple independently
    with propagating surface plasmon polaritons (SPPs) of Ag NW in quite different
    ways, thanks to the orientations of transition dipoles. Consistent with the simulations,
    the dark excitons and dark trions show extremely high coupling efficiency with
    SPPs, while the trions demonstrate directional chiral-coupling features. This
    study presents a crucial step towards the ultimate goal of exploiting the comprehensive
    spectrum of TMD excitons for optical information processing and quantum optics.
