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…
Light matter interaction in van der Waals heterostructures with Mie voids
Zhuoyuan Lu, Kirill Koshelev, Pavel Tonkaev +5
Recently introduced concept of Mie voids allows to enhance the field localization inside air cavities embedded in high-index materials. Mie voids provide an alternative approach to…
Light-cone-proximal quasi-BICs for chiral lasing at grazing angles
Dmitrii Gromyko, Cheng-Wei Qiu, Kirill Koshelev +1
Chiral quasi-bound states in the continuum (q-BICs) have recently emerged in metaphotonics as resonances that combine ultrahigh quality factors with near-unity circular polarizatio…
Resonant helical dichroism in twisted dielectric metastructures
Yiyuan Wang, Chi Li, Haoyi Yu +4
Circular dichroism, arising from interactions with light fields of opposite spin angular momentum, has become a fundamental tool for molecular characterization. Meanwhile, helical…
