THz radiation emission by phonon-polariton coupling in a semiconductor microcavity — •Katharina Rojan^1,2,3, Giovanna Morigi³, Maxime Richard^4,5, and Anna Minguzzi^1,2 — ¹Université Grenoble Alpes, LPMMC, Grenoble, France — ²CNRS, LPMMC, Grenoble, France — ³Theoretische Physik, Universität des Saarlandes, Saarbrücken, Germany — ⁴Université Grenoble Alpes, Institut Néel, Grenoble, France — ⁵Université Grenoble Alpes, Institut Néel, Grenoble, France

We suggest a scheme to generate THz radiation emission out of a semiconductor microcavity in the strong coupling regime. For this purpose we consider a model of interacting excitons, photons, and phonons which we describe by coupled Heisenberg-Langevin equations. We investigate the conditions necessary to achieve and optimize the THz emission and analyse the characteristics of the emitted photons. Furthermore we discuss a possible experimental realization using state-of-the-art semiconductor microcavities.
