Band Engineering of Exciton Polaritons in Resonant Polaritonic Metasurfaces
Polina Pantiukhina, Daria Smirnova, Kirill Koshelev
Polaritonic metasurfaces provide a versatile platform for engineering hybrid light-matter states through the interplay of optical resonances and excitonic excitations. Yet, predict…
Crystal orientation enables near-unity nonlinear circular dichroism in resonant metasurfaces
Chi Wang, Dmitrii Gromyko, Polina Pantiukhina +2
Achieving near-unity nonlinear circular dichroism (CD) typically requires geometric symmetry breaking, making it challenging to combine helicity selectivity, resonant enhancement,…
Optical Resonances: From Eigenmodes to Scattering Features
Ilya Karavaev, Kirill Koshelev, Andrey Bogdanov
Electromagnetic resonances play a central role in nanophotonics by enabling efficient confinement of electromagnetic energy and enhanced light-matter interaction. Traditionally, re…
