Deep learning enables large-scale inverse design of free-form metasurfaces
Viktor A. Lilja, Khosro Zangeneh Kamali, Mikael Käll +1
Metasurfaces are ultrathin optical elements that control light through carefully engineered structures smaller than the wavelength of light, enabling compact devices with functiona…
Microscopic Metavehicles Powered and Steered by Embedded Optical Metasurfaces
Daniel Andrén, Denis G. Baranov, Steven Jones +3
Nanostructured dielectric metasurfaces offer unprecedented opportunities to manipulate light by imprinting an arbitrary phase-gradient on an impinging wavefront. This has resulted…
Circular dichroism mode splitting and bounds to its enhancement with cavity-plasmon-polaritons
Denis G. Baranov, Battulga Munkhbat, Nils Odebo Länk +3
The ability to differentiate chiral molecules of different handedness is of great importance for chemical and life sciences. Since most of the relevant chiral molecules have their…
Resonant coupling between localized plasmons and anisotropic molecular coatings in ellipsoidal metal nanoparticles
Tobias Ambjornsson, Gautam Mukhopadhyay, S. Peter Apell +1
We present an analytic theory for the optical properties of ellipsoidal plasmonic particles covered by anisotropic molecular layers. The theory is applied to the case of a prolate…
