In this work, we have demonstrated tunable Rabi oscillations of exciton-polariton in the lead halide perovskite microcavity, which experiences the phase transition from orthorhombic through tetragonal to cubic phases for varying temperatures. The Rabi splitting can be tuned by the emergence of ferroelectricity to modify the exciton oscillator strength in the noncentrosymmetric tetragonal phase, where the oscillator strength and Rabi splitting are minimized. Our results provide an insight into the emerging functionalities of polariton devices by utilizing the ferroelectric semiconductors, which enable the realization of tunable quantum devices.
