Properties of polaritons in triple-Λ EIT system are investigated using Sawada-Brout-Chong method. The role of dark and bright-state polaritons in the dynamics of the system is studied in detail by including the decay of excited atomic levels. Time evolution of entanglement of single and three-photon EIT modes within the system is investigated to explain this study.
