BIO:

Femius Koenderink studied physics and mathematics at Utrecht University, and obtained a PhD at the University of Amsterdam (2003) pursuing photonic crystals. As postdoc at ETH Zürich he was first exposed to near field microscopy and the then emerging fields of plasmonic antennas for single emitters. He started his own group at AMOLF in 2008. The central theme of his research is to control emission, amplification and transport of light, down to the level of single emitters and single photons, using designer strongly scattering nanophotonic systems that are borrowed from the fields of plasmonics and metamaterials. Hand in hand with these pursuits the group develops optical techniques, such as polarimetric and interferometric Fourier microscopy. Part of his work is with industry, including projects on light emitting metasurfaces for solid state lighting, and on scatterometry for semiconductor metrology.

TALK: "Amplifying and nonlinear metasurfaces"

Metasurfaces that support high-Q Fano resonances due to bound states in the continuum (BICs) offer unique opportunities as linear and nonlinear light emitting metasurfaces. We are interested in the spatiotemporal physics and control of these intrinsically multimode structures. I will report recent results using femtosecond spectroscopy and Fourier microscopy, and engaging optical gain as well as instantaneous second and third order nonlinearities in systems with BICs. I will highlight a study of spontaneous symmetry breaking in plasmon lattice lasers, discuss a technique to map temporal dynamics and beating of near fields in BIC systems, and showcase spatiotemporal control of nonlinear light generation.
