We report exciton-polariton laser operation under electrical pumping. The hybrid light-matter nature of this lasing system is probed by measuring the exciton-polariton Zeeman-splitting, which clearly reveals that this laser remains in the strong coupling regime.
Exciton-polaritons are hybrid light-matter quasiparticles. They are composite and interacting bosons which can condense dynamically in a single-particle ground state via stimulated scattering. The formation of exciton-polaritons under electrical pumping has been demonstrated in quasi two dimensional systems [1–3]. In this work, we discuss the non-linear polariton emission caused by stimulated scattering...
