Platforms enabling control over strong light–matter interactions in optical cavities provide a challenging but promising way to manipulate emergent light–matter hybrids. Spin selectivity of transitions has now been demonstrated in a two-dimensional hole gas microcavity system, paving the way towards the study of new spin physics phenomena in hybrid excitations.
