Generation and Control of Coherent Terahertz Phonons in Silicon Metasurfaces Open
Semiconductor nanostructures are used in many applications, from electronics to nanophotonics to cite just a few, and most of these applications are based on silicon or silicon‐related technologies. With the miniaturization of these nanosc…

2D Waveguided Bessel Beam Generated Using Integrated Metasurface-Based Plasmonic Axicon Open
Near-field imaging of the propagation of a diffraction-free Bessel-type beam in a guided wave configuration generated by means of a metasurface-based axicon lens integrated on a silicon waveguide is reported. The operation of the axicon le…

Revealing a mode interplay that controls second harmonic radiation in gold nanoantennas Open
In this work, we investigate the generation of second harmonic light by gold nanorods and demonstrate that the collected nonlinear intensity depends upon a phase interplay between different modes available in the nanostructure. By recordin…

Energy-Resolved Hot-Carrier Relaxation Dynamics in Monocrystalline Plasmonic Nanoantennas Open
Hot carriers are energetic photo-excited carriers driving a large range of chemico-physical mechanisms. At the nanoscale, an efficient generation of these carriers is facilitated by illuminating plasmonic antennas. However, the ultrafast r…
