## Description

- description: 'Spectrally narrow optical resonances can be used to generate slow
    light, i.e., a large reduction in the group velocity. In a previous work, we developed
    hybrid 2D semiconductor plasmonic structures, which consist of propagating optical
    frequency surface-plasmon polaritons (SPPs) interacting with excitons in a semiconductor
    monolayer layer. In this work, we utilize coherent population oscillations of
    coupled exciton-SPPs in monolayer WSe2 to demonstrate slow light,  a ~600 fold
    decrease of the group velocity. Specifically, we use a two-color laser technique
    where the coupling between the two laser fields gives rise to a narrow ~3 µeV
    coherent population oscillation resonances, that result in a group velocity on
    order of 105 m/s. Our work paves the way toward on-chip actively switched delay
    lines and optical buffers that utilize 2D semiconductors. '
