Ultrafast tuning of the focusing efficiency of a nonlinear atomically thin lens
Rahil Rezwan, Bernardo Dias, Tom Hoekstra +10
Control over light focusing is paramount for optical and imaging systems. However, its implementation in active and integrated nanophotonic devices is hindered by the bulky and sta…
Finite-Size Effects in Nonlocal Metasurfaces
Tom Hoekstra, Sander A. Mann, Jorik van de Groep
Metasurfaces leveraging nonlocal resonances enable narrowband spectral control and strong near-fields, with applications spanning augmented reality, biosensing, and nonlinear optic…
