Resonant subspace approximation for photonic crystal slabs

Nikolay A. Gippius, Ilia M. Fradkin, Natalia S. Salakhova +1

Resonant approximations are indispensable for the interpretation and efficient modeling of photonic crystal slabs, yet most of them describe an eigenmode as a pole in the complex e…

Casimir effect in twisted photonic gratings with in-plane chirality

Natalia S. Salakhova, Sergey A. Dyakov, Ilia M. Fradkin +1

We investigate the Casimir effect in a system of two twisted photonic gratings made of uniaxially anisotropic materials. Two distinct configuretions are explored: a stack of symmet…

Plasmonic grating for circularly-polarized out-coupling of waveguide-enhanced spontaneous emission

I. M. Fradkin, A. A. Demenev, V. D. Kulakovskii +2

Plasmonic metasurfaces form a convenient platform for light manipulation at the nanoscale due to their specific localized surface plasmons. Nevertheless, despite the high degree of…
