Exciton-polaritons are quasiparticles that form upon strong coupling between electronic excitations of a material and photonic states of a surrounding microcavity. In semiconducting single-walled carbon nanotubes the special nature of excited states leads to particularly strong coupling even at room temperature (Nature Comm. 2016, 7, 13078). While emission from exciton-polaritons is usually created by optical excitation, the high ambipolar charge carrier mobilities of single-walled carbon nanotubes make them suitable for electrically driven polariton light-emitting devices with extended functionalities. We show that strong coupling and near-infrared exciton-polaritons can be generated and tuned in light-emitting field-effect transistors with integrated microcavities.
