Dipole-quadrupole model and multipole analysis of resonant membrane metasurfaces
Izzatjon Allayarov, Andrey B. Evlyukhin, Antonio Calà Lesina
Membrane-metasurfaces, formed by periodic arrangements of holes in a dielectric layer, are gaining attention for their easier manufacturing via subtractive techniques, unnecessity…
Strong coupling of collective optical resonances in dielectric metasurfaces
Izzatjon Allayarov, Vittorio Aita, Diane J. Roth +5
Dielectric metasurfaces can achieve strong light-matter interaction based on several types of collective (nonlocal) resonances, such as surface lattice resonances (SLRs) and quasi…
Topology optimization of a superabsorbing thin-film semiconductor metasurface
Johannes Gedeon, Izzatjon Allayarov, Emadeldeen Hassan +1
We demonstrate a computational inverse design method for optimizing broadband-absorbing metasurfaces made of arbitrary dispersive media. Our figure of merit is the time-averaged in…
Time-domain topology optimization of power dissipation in dispersive dielectric and plasmonic nanostructures
Johannes Gedeon, Izzatjon Allayarov, Antonio Calà Lesina +1
We present a density-based topology optimization scheme for locally optimizing the electric power dissipation in nanostructures made of lossy dispersive materials. By using the com…
Understanding the nonlinear optical response of epsilon near zero materials in the time-domain
Joshua Baxter, Adriana Pérez-Casanova, Luis Cortes-Herrera +3
The promise of active nanophotonics technology relies on the confinement and control of light at the nanoscale. Confinement via plasmonics, dielectric resonators, and waveguides ca…
