Exciton–Polaritons in Hybrid and Monolithic Nanophotonic Structures: A Review

초록

Exciton–polaritons are hybrid bosonic quasiparticles formed by the strong light–matter coupling between excitons and photons in photonic structures. In the past few decades, most exciton-polariton research has been carried out in vertical microcavities based on Bragg reflectors incorporating a wide range of excitonic materials. However, exciton-polariton research is now being supported by the rapid development of various nanophotonic platforms beyond the vertical microcavities. This paper reviews recent advances in nanophotonic platforms such as waveguides, photonic crystals, and metasurfaces. Furthermore, we specifically present exciton–polaritons realized in self-resonant, monolithic nanophotonic structures formed directly from excitonic materials without relying on external cavity structures.
