Enhanced generation of non-degenerate photon-pairs in nonlinear metasurfaces
Matthew Parry, Andrea Mazzanti, Alexander Poddubny +3
We reveal a novel regime of photon-pair generation driven by the interplay of multiple bound states in the continuum resonances in nonlinear metasurfaces. This non-degenerate photo…
Photoinduced Temperature Gradients in Sub-wavelength Plasmonic Structures: The Thermoplasmonics of Nanocones
Joao Cunha, Tian-Long Guo, Alemayehu Nana Koya +5
Plasmonic structures are renowned for their capability to efficiently convert light into heat at the nanoscale. However, despite the possibility to generate deep sub-wavelength ele…
Shortcut to adiabaticity in full-wave optics for ultra-compact waveguide junctions
Giuseppe Della Valle, Gerardo Perozziello, Stefano Longhi
We extend the concept of shortcut to adiabaticity to full-wave optics and provide application to the design of an ultra-compact waveguide junction. In particular, we introduce a pr…
Nonlinear anisotropic dielectric metasurfaces for ultrafast nanophotonics
Giuseppe Della Valle, Ben Hopkins, Lucia Ganzer +7
We report on the broadband transient optical response from anisotropic nanobrick amorphous silicon particles, exhibiting Mie-type resonances. A quantitative model is developed to i…
Loss-induced lasing: new findings in laser theory?
Stefano Longhi, Giuseppe Della Valle
In a recent work, using a coupled microresonator system with tailored gain and loss parameters B. Peng et al. [Science 346, 328 (2014)] have experimentally reported on an apparentl…
Thermo-modulational interband susceptibility and ultrafast temporal dynamics in nonlinear gold-based plasmonic devices
Andrea Marini, Matteo Conforti, Giuseppe Della Valle +7
Starting from first principles, we theoretically model the nonlinear temporal dynamics of gold-based plasmonic devices resulting from the heating of their metallic components. At o…
