    Polarization Independent Unidirectional Scattering With Turnstile Nanoantennas

    Polarization Independent Unidirectional Scattering With Turnstile Nanoantennas by Davide Rocco, Michele Midrio, Costantino De Angelis

    Published 2020-01-01

    We study the scattering behavior of a dielectric cross-dipole nanoantenna in the near-infrared spectral range when it is excited by a circular polarized plane wave. We theoretically demonstrate, for optimized geometrical parameters of the proposed turnstile structure, the possibility to simultaneous...

    Vertical Second Harmonic Generation in Asymmetric Dielectric Nanoantennas

    Vertical Second Harmonic Generation in Asymmetric Dielectric Nanoantennas by Davide Rocco, Carlo Gigli, Luca Carletti, Giuseppe Marino, Maria Antonietta Vincenti, Giuseppe Leo, Costantino De Angelis

    Published 2020-01-01

    High-permittivity III–V semiconductor nanocavities have shown huge potential for enhanced nonlinear light–matter interactions at the nanoscale. In particular, Second Harmonic (SH) generation in AlGaAs nanoantennas can be extremely efficient; however, vertical emission is diffic...
