Several experimental and theoretical procedures have been used to get the Bose
Einstein Condensation (BEC) of polaritons. Nowadays, the investigation of the BEC of
polaritons is vastly popular and increasing attention in atomic as well as solid-state physics
because it has many technological applications. In this chapter, different experimental
procedures, excitation, and observation methods are explained. Recent research developments
in this field and the application of the BEC also are discussed.
Keywords: Application of polariton condensation, Bose Einstein Condensation of polaritons, Experimental techniques to get polariton condensation, Optical observation methods, Theoretical modeling to get polariton condensation.
