Matthijs Berghuis obtains his PhD!
We congratulate Matthijs for graduating with his thesis Strong Light-Matter Coupling in Organic Crystals, which was defended in Eindhoven on April 20.
Chasing Vibro-Polariton Fingerprints in Infrared and Raman Spectra Using Surface Lattice Resonances on Extended Metasurfaces
We present an experimental investigation of vibrational strong coupling of C═O bonds in poly(methyl methacrylate) to surface lattice resonances (SLRs) on arrays of gold particles in infrared and Raman spectra. Despite clear evidence of vibrational strong coupling in IR transmission spectra, both Raman spectroscopy and micro-Raman mapping do not show any polariton signatures. Our results…

Nano-WiCom granted!
NWO has announced that the collaboration project Nano-WiCom between the departments of Applied Physics and Electrical Engineering has been granted in the Open Technology Program. The goal of Nano-WiCom is to realize very low étendue (beamed) and efficient emission at a very fast rate (sub-100 picosecond) and to detect this emission with fast integrated photodetectors. This goal…

Center for Terahertz Science & Technology Eindhoven
On Wednesday July 14th the foundation of the Center for Terahertz Science & Technology Eindhoven (CTSTe) was announced. This center is initiated from a common interest and ambition to be at the forefront of the quickly evolving field of THz science, to push THz technology forward, and to apply this technology in different fields relevant for society.
Niels van Hoof successfully defends his PhD thesis
On June 3rd, 2021 has Niels van Hoof defended his Ph.D. thesis titled “Mapping Ultrafast Electric Fields using Terahertz Microscopy”. During his Ph.D., Niels has developed a unique THz near-field microscope that has enabled the investigation of resonances in surfaces at THz frequencies that were inaccessible before. The Cursor has written an article about Niels’…

Effective Negative Diffusion of Singlet Excitons in Organic Semiconductors
We have studied the diffusion of singlet and triplet excitons in tetracene crystals, a prototype singlet fission material, using ultrafast microscopy techniques. Upon laser excitation, triplets diffuse steadily while the singlet exciton distribution narrows, corresponding to an effective negative singlet diffusion. This counterintuitive result is explained by nonlinear triplet‒triplet annihilation. View the article in the Journal…
