Hybrid-2D Excitonic Metasurfaces for Complex Amplitude Modulation
Tom Hoekstra, Mark L. Brongersma, Jorik van de Groep
Dynamic control of visible light is crucial for technologies such as holographic displays and adaptive optics. Passive metasurfaces can shape wavefronts at the subwavelength scale…
Temperature-dependent excitonic light manipulation with atomically-thin optical elements
Ludovica Guarneri, Qitong Li, Thomas Bauer +5
Monolayer 2D semiconductors, such as WS2, exhibit uniquely strong light-matter interactions due to exciton resonances that enable atomically-thin optical elements. Similar to geome…
Electrically tunable strong coupling in a hybrid-2D excitonic metasurface for optical modulation
Tom Hoekstra, Jorik van de Groep
Atomically thin semiconductors exhibit tunable exciton resonances that can be harnessed for dynamic manipulation of visible light in ultra-compact metadevices. However, the rapid n…
Mechano-optical metasurfaces
Freek van Gorp, Wenfeng Liu, Corentin Coulais +1
Tunable metasurfaces enable active and on-demand control over optical wavefronts through reconfigurable scattering of resonant nanostructures. Here, we present novel insights inspi…
