摘要

The hybrid plasmonic surface lattice resonance (SLR) laser constructed by a MAPbBr3 perovskite thin film on the Ag nanoparticle array is unambiguously demonstrated in this research. The relatively high refractive index of the perovskite thin film provides an excellent coupling between the photonic mode and SLR, leading to a high spontaneous emission coupling factor and a low threshold lasing. Furthermore, a novel spin-coating process applied to grow the MAPbBr3 perovskite thin film can leave air gaps under the perovskite that provides a large index difference in the periodic array, making the hybrid plasmonic SLR exhibits a high density of state, which is beneficial for laser operation. Via theoretical design and experimental verification, the lasing behaviors of the hybrid plasmonic SLR perovskite laser show excellent characteristics with a fixed polarization. This demonstration facilitates an enhanced lasing performance and realization of the low-cost and low-energy-consumption laser application.
