N2 - The polarization-coupled exciton-polariton is promising for applications in polarization-associated optoelectronic devices. Although a room-temperature exciton-polariton has been observed in many nanostructures, super-broad-wavelength-range polarization-selective excitonpolariton output remains elusive. Here, a room-temperature exciton-polariton is demonstrated by angle-resolved photoluminescence (ARPL) spectroscopy in Sn-doped CdS nanowires. Due to the reduction of cross-section radius, the polarization splitting between transverse electric (TE) and transverse magnetic (TM) modes increases. The maximum splitting value can reach 45 meV when the cross-section is 0.548 μm. Taking advantage of the interaction's polarization effect between the photon and exciton, polarization-selective exciton-polariton output is realized, and the wavelength tuning range is more than 200 nm. These results provide useful enlightenment to construct polarization polaritonic devices at room temperature.
