All-dielectric metasurfaces consisting of arrays of nanostructured high-refractive-index materials, typically Si, are re-writing what is achievable in terms of the manipulation of light. Such devices support very strong magnetic, as well as electric,

Due to their two-dimensional nature, transition metal dichalcogenide monolayers exhibit extremely strong sensitivity of their excitonic response to the permittivity of the surrounding medium. Here, we show that the intensity and wavelength of their e
