Active aerosols
Charles A. Rohde, Kristin M. Charipar, Paul Johns +3
We report the dynamics and control of the orientational and positional order of ensembles of gold nanorods suspended in air at standard temperature and pressure using externally ap…
Plasmonic Aerosols
Jeffrey Geldmeier, Paul Johns, Nicholas J. Greybush +2
Plasmonic nanoparticles resonantly couple to and confine light below the diffraction limit. This mechanism has enabled a modern renaissance in optical materials, with potential app…
Nonlinear refractive index of electric field aligned gold nanorods measured with a Hartmann-Shack wavefront aberrometer
Melissa Maldonado, Leonardo de S. Menezes, Leonardo F. Araujo +5
The capability to dynamically control the nonlinear refractive index of plasmonic suspensions may enable innovative nonlinear sensing and signaling nanotechnologies. Here, we exper…
Tunable subnanometer gap plasmonic metasurfaces
Dennis Doyle, Nicholas Charipar, Christos Argyropoulos +6
The index of refraction governs the flow of light through materials. At visible and near infrared wavelengths the real part of the refractive index is limited to less than 3 for na…
Digital electric field induced switching of plasmonic nanorods using an electro-optic fluid fiber
Sebastian Etcheverry, Leonardo F. Araujo, Isabel C. S. Carvalho +2
We demonstrate the digital electric field induced switching of plasmonic nanorods between 1 and 0 orthogonal aligned states using an electro-optic fluid fiber component. We show by…
