Third-harmonic Generation Microscopy of Metal Nanocones Using Cylindrical Vector Beams
For years, there has been a renewed interest in the unique focusing properties of cylindrical vector beams (CVB), i.e., beams which exhibit rotationally symmetric polarization states, and their novel imaging applications [1]. Particularly, it was found that focused CVBs can be used as versatile orientation probes for single molecules and metal nanostructures [1]. Orientation imaging of metal na...
متن کاملNanoscale optical properties of metal nanoparticles probed by Second Harmonic Generation microscopy.
We report spatial and vectorial imaging of local fields' confinement properties in metal nanoparticles with branched shapes, using Second Harmonic Generation (SHG) microscopy. Taking advantage of the coherent nature of this nonlinear process, the technique provides a direct evidence of the coupling between the excitation polarization and both localization and polarization specificities of local...
متن کاملDetecting the trapping of small metal nanoparticles in the gap of nanoantennas with optical second harmonic generation.
The second harmonic generation from gold nanoparticles trapped into realistic and idealized gold nanoantennas is numerically investigated using a surface integral equations technique. It is observed that the presence of a nanoparticle in the nanoantenna gap dramatically modifies the second harmonic intensity scattered into the far-field. These results clearly demonstrate that second harmonic ge...
متن کاملFabrication of Ion-Shaped Anisotropic Nanoparticles and their Orientational Imaging by Second-Harmonic Generation Microscopy
Ion beam shaping is a novel and powerful tool to engineer nanocomposites with effective three-dimensional (3D) architectures. In particular, this technique offers the possibility to precisely control the size, shape and 3D orientation of metallic nanoparticles at the nanometer scale while keeping the particle volume constant. Here, we use swift heavy ions of xenon for irradiation in order to su...
متن کاملUltrafast optical nonlinearities of metal nanoparticles: Single-particle measurements and correlation to structure
We have measured nonlinear scattering from plasmons in individual Au nanorods and have correlated second-harmonic activity of Ag nanoparticles and clusters to morphology. The measurements reveal novel ultrafast nonlinear phenomena related to electron confinement. Surprisingly, the coherent plasmon response is suppressed relative to the hot electron response indicating enhanced plasmon dephasing...
