Reciprocity is broken by optically self-induced phase transition of VO2 occurring at different intensities for the opposite directions of illumination.The authors acknowledge a support from the Australian Research Council (grants DE210100679 and DP210101292) and the EU Horizon 2020 Research and Innovation Program (grant 896735).enPublisher Copyright: © 2022 The Author(s)202285146740995
