In our recently published manuscript in Nano Letters, we have demonstrated the important role that vibrations in molecules have for the condensation and the emission of organic exciton-polariton lasers. You can find the manuscript in this link or read the news item.
We are proud that our work on photonics is presented at the Drivers of Change exhibition of the Dutch Design Week (DDW). The DDW is the biggest design event in Northern Europe. It attracts more than 350,000 visitors from home and abroad. The Drivers of Change exhibition of TU/e presents the latest developments in the…
The first interdepartmental start-up company, TeraNova B.V., has been founded (www.teranova.nl). TeraNova B.V. is an initiative of the Applied Physics research group Photonics and Semiconductor Nanophysics (Prof. Jaime Gómez Rivas) and Electrical Engineering research group Integrated Circuits (Prof. Marion Matters-Kammerer). Besides Gómez Rivas and Matters-Kammerer, also Dr. Mohammad Ramezani (Photonics and Semiconductor Nanophysics) and Ing. Corné…
Stan ter Huurne has given a keynote presentation at the IRMMW conference in Paris. Stan presented the work that he done together with Niels van Hoof on modes with infinite lifetime (bound states in the continuum) at THz frequencies. Niels also presented the work on THz near-field microscopy.
We have demonstrated a four-fold enhancement of the delayed fluorescence in tetracene crystals by strongly coupling singlet excitons to photons in an optical cavity formed by a nanoparticle array. The enhanced luminescence is attributed to triplet excitons that are harvested by the lower polariton band emerging from the strong coupling. These type of effects in…
Spectral and temporal evidence of robust photonic bound states in the continuum on terahertz metasurfaces
In collaboration with the group of Sanchez Gil (CSIC-Spain), we have demonstrated that a simple array of gold dimers can support modes with infinite life-times. We have investigated these, so-called, Bound States in the Continuum using THz time-domain spectroscopy. Read more in our published Optica.
Terahertz Time-Domain Spectroscopy and Near-Field Microscopy of Transparent Silver Nanowire Networks
In collaboration with our former colleages of the Dutch Institute for Fundamental Energy Research, we have measured the sheet conductance of transparent electrodes formed by networks of Ag nanowires. The measurements have been done in a contact-free manner and spatially resolved, using our newly developed THz near-field microscope. Read more in our published Advanced Optical…
