Abstract
We experimentally demonstrate a metasurface that supports tailorable polaritons arising from strong coupling between Mie modes of dielectric nanoresonators and intersubband transitions of semiconductor quantum wells that are embedded inside the resonator.

Fig. 2 (a) Experimentally measured reflectance spectrum of Mie resonators of different radii with MD resonances detuned from IST resonance. Reflectance curves are offset vertically for clarity. The dashed lines are shown as guide to eyes. Changing radii leads to linear scaling of the MD resonance. (b,c) Experimentally measured reflectance spectrum of Mie resonators of different radii with MD resonances spectrally overlapping with the ISBT. A clear anti-crossing behavior of the polariton branches is observed. The average doping densities of the QWs inside the resonators are 8x1017 cm-3 for (b) and 3x1018 cm-3 for (c). (d) Experimentally measured reflectance spectrum of Mie resonators of different radii with ED resonances spectrally overlapping with the IST resonance. The doping density of QWs is same as in (c). Much smaller Rabi splitting compared to (c) is observed.
