Strong exciton-photon coupling in self-hybridized organic-inorganic lead halide perovskite microcavities.

ABSTRACT: Controlling coherent light-matter interactions in semiconductor microcavities is at the heart of the next-generation solid-state polaritonic devices. Organic-inorganic hybrid perovskites are potential materials for room-temperature polaritonics owing to their high exciton oscillator strengths and large exciton binding energies. Herein, we report on strong exciton-photon coupling in the micro-platelet and micro-ribbon shaped methylammonium lead bromide single crystals. Owing to high crystallinity and large refractive index, the as-grown perovskite microcrystals serve as self-hybridized optical microcavities along different orientations due to their distinct physical dimensionalities. In this regard, the perovskite micro-platelet forms a simple Fabry-Perot microcavity in out-of-plane orienta
