Spectrally smooth broadband response via autocorrelation-constrained inverse design
Johannes Gedeon, Rasmus E. Christiansen, Rasmus Ellebæk Christiansen +1
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…
