Scientists demonstrate transition between strong and weak coupling regimes in a polariton microcavity

Researchers from Skoltech, together with colleagues from the N. D. Zelinsky Institute of Organic Chemistry and Westlake University, have experimentally demonstrated how the operating regime of a polariton laser changes with a gradual increase in cavity thickness.
