Abstract

In this work, we report an amplified strong coupling phenomenon in a hybridized nanowire. The hybridized nanowire structure is composed of CH₃NH₃PbBr₃ perovskite nanowire coated by SiO₂ film and silver film. Due to the existence of silver film, Rabi splitting in hybrid structure can reach 303.2 meV, while the Rabi splitting in a pure perovskite nanowire is only 236.4 meV. Also, thicknesses of SiO₂ film and Ag film can control the Rabi splitting of hybridized structure: (i) the thicker the Ag film, the greater the Rabi splitting; (ii) the thinner the SiO₂ film, the greater the Rabi splitting. Finally, index of SiO₂ film shows a linear relation with Rabi splitting.
