A research team from Skoltech and ITMO university has obtained tunable polariton emission at room temperature on CsPbBr3 perovskite crystals as a promising platform for integration into lateral microchips—a new concept for the integrated all-optical logic that Skoltech researchers are working on.
The research results are presented in the Advanced Optical Materials journal.
Exciton-polaritons are hybridized states of light and matter, which are formed as a result of strong interaction of optical modes of microcavity—photons—with elementary excitations of a material—excitons.
