Here, we describe a structure in which a strongly coupled microcavity containing an organic semiconductor is coupled to a second microcavity containing a series of weakly coupled inorganic quantum wells. We show that optical hybridisation occurs between the optical modes of the two cavities, creating a delocalised polaritonic state. By electrically injecting electron-hole pairs into the inorganic quantum-well system, we are able to transfer energy between the cavities and populate organic-exciton polaritons. Our approach represents a new strategy to create highly efficient devices for emerging 'polaritonic' technologies.Light, science & applicationsA hybrid organic-inorganic polariton LED.PMC6804868smru10001EP/M025330/1DTG allocation1572383Rajendran SKGeorgiou KClark JAskitopoulos AMusser AJSamuel IDWTurnbull GAColes DMLagoudakis PGCoulthard HLidzey DGJayaprakash RfalseA hybrid organic-inorganic polariton LED.Polaritons are quasi-particles composed of a superposition of excitons and photons that can be created within a strongly coupled optical microcavity.
