Nanosecond mid-infrared pulse generation via modulated thermal emissivity
Yuzhe Xiao, Nicholas A. Charipar, Jad Salman +2
We demonstrate the generation of nanosecond mid-infrared pulses via fast modulation of thermal emissivity, enabled by the absorption of visible pump pulses in unpatterned silicon a…

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…
