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.
