We realize a Perot-Fabry hybrid microcavity containing an association of a ZnO thin layer and of a layer of the two dimensional layered perovskite 5-methyl-2-furanmethanamonium lead bromide (MFMPB). From angle-resolved reflectivity experiments performed at low temperature of 5K, we show that this hybrid cavity works in the strong coupling regime and that the lower, middle and upper polariton branches are observed. We show that the Middle Polariton Branch (MPB) contains a significant component of the cavity photon and both of the two exciton species.
