To reveal and utilize the interaction between Tamm plasmon polaritons (TPPs) and two-dimensional materials are promising for exploiting next-generation optoelectronic devices. Herein, the coupling mechanism between metal TPPs and monolayer WS2 along with its differences from that between metal TPPs and graphene was studied in detail by using the transfer matrix method. The experimental results show that it is difficult to excite TPPs at the boundary between monolayer WS2 and dielectric Bragg reflector (DBR) such that the strong coupling mainly stems from the interaction between metal TPPs and exciton in monolayer WS2. However, the coupling in graphene/DBR/metal hybrid structure derives from the interaction between two different TPP resonance modes. Thus, evolutions of Rabi splitting with various structural parameters including spacer thickness, incident angle and DBR period greatly differ from those observed in graphene/DBR/metal hybrid structure. In addition, the discrepancies induced via metal Ag and Au films as well as the possible influence mechanism were also discussed.
