Plasmonic-cavity Modulator for the Mid-IR with a Semi-transparent and Nonlinear Heavily-doped Semiconductor Mirror
Tommaso Venanzi, Raffaella Polito, Andrea Rossetti +15
We present a free-space plasmonic modulator based on a single heavily-doped semiconductor layer. We investigate its ability to modulate both the linear and nonlinear response at mi…
Ultrahigh free-electron Kerr nonlinearity in all-semiconductor waveguides for all-optical nonlinear modulation of mid-infrared light
Gonzalo Álvarez-Pérez, Huatian Hu, Fangcheng Huang +3
Nonlinear optical waveguides, particularly those harnessing the optical Kerr effect, are promising for advancing next-generation photonic technologies. Despite the Kerr effect`s ul…
Modulating Low-Power Threshold Optical Bistability by Electrically Reconfigurable Free-Electron Kerr Nonlinearity
Huatian Hu, Gonzalo Álvarez-Pérez, Antonio Valletta +3
We propose a microscopic mechanism to electrically reconfigure the Kerr nonlinearity by modulating the concentration of free electrons in heavily doped semiconductors under a stati…
Origin of optical nonlinearity in plasmonic semiconductor nanostructures
Andrea Rossetti, Huatian Hu, Tommaso Venanzi +15
The development of nanoscale nonlinear elements in photonic integrated circuits is hindered by the physical limits to the nonlinear optical response of dielectrics, which requires…
Boosting infrared energy transfer in 3D nanoporous gold antennas
D. Garoli, E. Calandrini, A. Bozzola +5
The applications of plasmonics to energy transfer from free-space radiation to molecules are currently limited to the visible region of the electromagnetic spectrum due to the intr…
