Abstract

In this paper, meta-surface with electromagnetically induced-reflection-like (EIR-like) dispersion is introduced to enhance the optical Tamm state (OTS) and related lasing effect. Numerical analysis and full-wave simulation confirm that this structure-induced EIR-like dispersion of meta-surface gives rise to the Q-factor of OTS. Consequently, enhanced lasing effect also is investigated when a four-level two-electron atomic system is introduced. The results show that the lasing threshold can almost be reduced to half, with the enhancement of max emission intensity in the mean time. These features make the meta-surface-enhanced OTS structure promising for reducing the lasing threshold, enhancing the fluorescence, and so on.
