Light at the nanoscale: How can we measure it and what can we do with it? (Ulrich Hohenester, Graz)

Nov 02, 2021 from 04:15 PM

Hybrid, Physikalisches Kolloquium

Ulrich HohenesterNano-Optics is concerned with the manipulation of light at or beyond the diffraction limit. Light confinement in subwavelength volumes is achieved by binding light to plasmonic or phononic resonances of nanoparticles. In this talk, I will first report on our efforts to measure and reconstruct the three-dimensional vectorial fields in nanophotonic environments, using electron energy loss spectroscopy (EELS), a technique based on electron microscopy, together with plasmon field tomography [1]. With the newest generation of electron microscopes, the energy resolution can be further pushed to the meV range and it becomes possible to image the surface and bulk phonon polariton fields in ionic nano­structures [2]. Recently, we have reconstructed the three-dimensional vectorial fields of such phononic nanostructures from a series of tilted EELS images [3].

In the second part of this talk, I will report on an unrelated subject of real-time nanoparticle characterization using optical forces and torques exerted by a focused Laguerre-Gaussian laser beam with an orbital angular momentum [4]. With this setup we demonstrate real-time optical counting of nanoparticles in a microfluidic channel with single-particle sensitivity, high through­put, and for particle sizes ranging from tens of nanometers to several micrometers. Such nanoparticle counting is crucial for numerous pharmaceutical and technological applications, as well as for medical diagnostics.
