Low-power threshold optical bistability enabled by hydrodynamic Kerr nonlinearity of free-carriers in heavily doped semiconductors
Huatian Hu, Gonzalo Álvarez-Pérez, Tadele Orbula Otomalo +1
We demonstrate nanoscale optical bistability at an exceptionally low power threshold of 1 mW by leveraging Kerr-type hydrodynamic nonlinearities due to the heavily doped semiconduc…

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…
