Abstract

Exploring exciton-polariton effects in low dimensional semiconductors with large oscillation strength provides solutions to develop low threshold lasers and low-energy consumption, fast photonic interconnections. In this talk, I will introduce our recent results on surface plasmon enhanced exciton-polariton of perovskite nanowires. We find that Rabi splitting energy of MAPbBr3 nanowires is enhanced by 40% by adopting a semiconductor nanwire/dielectric/Ag film sandwich structure. A Rabi splitting energy up to 595 meV is achieved as the dielectric thickness is 5 nm. Later, we demonstrated a room temperature, low-threshold green plasmonic laser in the same configuration.
