Abstract
The ZnO‐based Tamm plasmon‐polariton (TPP) ultraviolet laser is realized with the strong electric field confinement in the active layer. A coupling between TPPs and photons with a Rabi splitting of ≈30 meV is observed at room temperature. Furthermore, the TPP lasing at 373 nm is clearly observed by optical pumping. The corresponding lasing characteristics, such as threshold energy, linewidth, and angular dispersion curve are verified. These results form a basis for better understanding of the TPPs lasing mechanisms.
