Invited Speaker / Conférencier invité
Recent advances in nanofabrication made it possible to produce arrays of artificial structures (metamolecules) with good optical quality. This, in turn, enabled the observation of many unusual phenomena, such as invisibility cloaking, negative refraction, generation of beams with orbital angular momentum and other modifications to the polarization state of the incoming light. Of special...

Nonlinear optical microscopy techniques, such as stimulated Raman scattering (SRS) and coherent anti-Stokes Raman scattering (CARS), allow for label-free chemically-sensitive non-destructive video-rate imaging of biological processes[1]. SRS is of particular interest due to its improved image contrast, high spectral sensitivity and low acquisition times.
Correctly interpreting images produced...

Radially and azimuthally polarized light beams have garnered increased interest for their properties and uses in fundamental and applied optics. Radial polarizations are parallel to the central axis of the beam (at all points pointing toward the beam center); azimuthal polarizations are orthogonal to this, running perpendicular to the central axis of the beam. Photon pairs with these...

Light fields with spatially varying polarization have a wide range of potential uses in the areas of telecommunication, imaging, lithography, and quantum information. A spatial light modulator (SLM) is a two dimensional array of liquid crystal cells that can control phase, polarization, and intensity of light point by point across a beam’s spatial profile. We have developed methods to...

We demonstrated simultaneous all-optical, single-shot holographic measurement of attosecond high harmonic pulses and a femtosecond laser pulse. To achieve this, we introduce a weak laser beam into the harmonic generation medium together with the strong driving laser field. The weak laser field perturbs the trajectories of ionized electrons that are responsible for high harmonic generation and...
