Nonlinear plasmonic directional couplers
TL;DR: In this paper, the nonlinear modes of plasmonic directional couplers created by two nonlinear dielectric slot waveguides with metallic claddings are studied.
Journal ArticleDOI
Bistability of anderson localized States in nonlinear random media.

TL;DR: This work reveals that, while weak nonlinearity does not change the typical exponentially small transmission in the regime of the Anderson localization, it affects dramatically the disorder-induced localized states excited inside the medium leading to bistable and nonreciprocal resonant transmission.
Journal ArticleDOI
Nonlinear Anisotropic Dielectric Metasurfaces for Ultrafast Nanophotonics
Giuseppe Della Valle,Ben Hopkins,Lucia Ganzer,Tatjana Stoll,Mohsen Rahmani,Stefano Longhi,Yuri S. Kivshar,Costantino De Angelis,Dragomir N. Neshev,Giulio Cerullo +9 more
TL;DR: In this paper, a quantitative model is developed to identify and disentangle the three physical processes that govern the ultrafast changes of the nanobrick optical properties, namely, two-photon absorption, free-carrier relaxation, and lattice heating.
Journal ArticleDOI
Tunable transmission and bistability in left-handed bandgap structures
TL;DR: In this article, the defect-induced nonlinear transmission of a periodic structure created by alternating slabs of two materials with positive and negative refractive index was studied, and bistable switching and tunable non-linear transmission in a novel type of bandgap was demonstrated.
