It is shown that the later polaritons will be achieved as the perovskite layer is ultra-thin (&lt;50 nm), while the co-existence of both polaritons will dominate, as the thickness of the perovskite metasurface approaches wavelength-scale. In the two cases, the lower polaritonic branches consist of dark and bright modes corresponding to infinite and finite radiative quality factors, respectively. Another salient property in this work is that it allows one to obtain exceptional points (EPs) in momentum space with a four-fold enhancement of local density of states through engineering the perovskite metasurface. Our findings show that the perovskite metasurface is an attractive and rich platform to make polaritonic devices, even with the presence of a lossy metallic layer.<\/p>\n<p>Authors: Le Van, Q. and other authors<\/p>\n<p>Read more about the article\u00a0<a href=\"https:\/\/www.osapublishing.org\/DirectPDFAccess\/A165B94C-46A7-4670-A439B05AB43715F5_442611\/prj-8-12-A91.pdf?da=1&amp;id=442611&amp;seq=0&amp;mobile=no\">here<\/a><\/p>\n<p>Read more about the author\u2019s publications\u00a0<a href=\"https:\/\/vinuni.edu.vn\/people\/quynh-v-le\/\">here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Abstract We present theoretically the formation of exciton\u2013photon polaritons and exciton-surface plasmon polaritons in a perovskite-based subwavelength lattice on the metallic plane.
