Localization of signals is a widely applied technique used in different areas of science telecommunication, medicine, or seismology. In this work, we study microseismic emissions due to stick-slip events during pneumatic fracture in a transparent set

We investigate second- and third-harmonic generation from individual AlGaAs nanoantennas using far-field mapping with radially- and azimuthally-polarized cylindrical vector beams. Due to the unique polarization structure of these beams, we are able t

We present an in situ microscopic technique to calibrate phase-only liquid-crystal-based spatial light modulators LC SLM). The technique relies on the spatial structure of focused fields that are commonly encountered in optical microscopy. To retrie

Efficient optical excitation of hybridized plasmon modes in nanoantennas is vital to achieve many promising functionalities, but it can be challenging due to a field-profile mismatch between the incident light and the hybrid mode. We present a genera

We demonstrate the tailoring of longitudinal electric fields that arise from tight focusing of spatially phase-shaped high-order laser beams, and verify their spatial distribution in three dimensions. To tailor the three-dimensional (3D) spatial dist

Longitudinally polarized optical needles are beams that exhibit ultra-long depth of field, subwavelength transverse confinement, and polarization oriented along the longitudinal direction. Although several techniques have been proposed to generate su

By means of digital image correlation, we experimentally characterize the deformation of a dry granular medium confined inside a Hele-Shaw cell due to air injection at a constant overpressure high enough to deform it (from 50 to 250 kPa). Air injecti

We use second- and third-harmonic generation with cylindrical vector beams to investigate AlGaAs nanodisks. The nonlinear emission is found to depend strongly on the interplay between tensorial nonlinearities, focal-field symmetries and resonant mult

We employ structured light to study resonantly-enhanced second- and third-harmonic emission from AlGaAs nanoantennas. We demonstrate correlation between nonlinear emissions with the pump polarization state and Mie-resonant excitation.
