Spectrally smooth broadband response via autocorrelation-constrained inverse design
Johannes Gedeon, Rasmus Ellebæk Christiansen, Ole Sigmund
Time-domain inverse design in photonics is known to be suitable for maximizing the efficiency of optical devices over broad frequency ranges. Objectives commonly used in this conte…
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…
Free-form inverse design of arbitrary dispersive materials in nanophotonics
Johannes Gedeon, Emadeldeen Hassan, Antonio Calà Lesina
In the last decades nanostructures have unlocked myriads of functionalities in nanophotonics by engineering light-matter interaction beyond what is possible with conventional bulk…
Machine learning the derivative discontinuity of density-functional theory
Johannes Gedeon, Jonathan Schmidt, Matthew J. P. Hodgson +3
Machine learning is a powerful tool to design accurate, highly non-local, exchange-correlation functionals for density functional theory. So far, most of those machine learned func…
