摘要： A new type of cavity polariton, the optical Tamm state (OTS) polariton, is proposed to be realized by sandwiching a quantum well (QW) between a gold layer and a distributed Bragg reflector (DBR). It is shown that OTS polaritons can be generated from the strong couplings between the QW excitons and the free OTSs. In addition, if a second gold layer is introduced into the bottom of the DBR, two independent free OTSs can interact strongly with the QW excitons to produce extra OTS polaritons.
