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…
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…
Sharp spectral variations of the ultrafast transient light extinction by bimetallic nanoparticles in the near-UV
Tadele Otomalo, Lorenzo Di Mario, Cyrille Hamon +6
Noble metal nanoparticles exhibit localized plasmon resonance modes that span the visible and near-infrared spectral ranges and have many applications. Modifying the size, shape, a…
