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…
