Electric field-controlled reversible order-disorder switching of a metal tip surface
Ludvig de Knoop, Mikael Juhani Kuisma, Joakim Löfgren +5
While it is well established that elevated temperatures can induce surface roughening of metal surfaces, the effect of a high electric field on the atomic structure at ambient temp…
Magnetoplasmonic design rules for active magneto-optics
Kristof Lodewijks, Nicolò Maccaferri, Tavakol Pakizeh +5
Light polarization rotators and non-reciprocal optical isolators are essential building blocks in photonics technology. These macroscopic passive devices are commonly based on magn…
Tuning the Fano resonance between localized and propagating surface plasmon resonances for refractive index sensing applications
Kristof Lodewijks, Jef Ryken, Willem Van Roy +3
Localized and propagating surface plasmon resonances are known to show very pronounced interactions if they are simultaneously excited in the same nanostructure. Here we study the…
Boosting the Figure Of Merit of LSPR-based refractive index sensing by phase-sensitive measurements
Kristof Lodewijks, Wim Van Roy, Gustaaf Borghs +2
Localized surface plasmon resonances possess very interesting properties for a wide variety of sensing applications. In many of the existing applications only the intensity of the…
Self-assembled hexagonal double fishnets as negative index materials
Kristof Lodewijks, Niels Verellen, Willem Van Roy +2
We show experimentally the successful use of colloidal lithography for the fabrication of negative index metamaterials in the near-infrared wavelength range. In particular, we inve…
