Plasmonic Waveguides and Antennas KU Leuven
The field of plasmonics has received great attention during the past years. Plasmonic devices are characterized by their small electrical size which enabled researchers to overcome the challenge of the size mismatch between the bulky photonic devices and the small electronic circuits. Plasmonic metals are characterized by their lossy dielectric nature which is different from the highly conductive classical metals. Consequently, the design of ...
A Volume Integral Equation (VIE) Algorithm for Modelling the Nonlocal Electromagnetic Response from a Deep Nanometer Scatterer KU Leuven
The recent grand leap in nanotechnology renders us the very capability of miniaturizing classical antennas down to the nanoscale and extends the concept of antennas from conventional RF frequencies to the optical regime. Very recently, the study of these nanoscale antennas, i.e. nanoantennas, has entered the so-called deep-nanometer regime, where the nanoantennas with characteristic dimensions of a few to tens of nanometers are considered. To ...
Plasmonic Devices Electrically Driven by Tunnel Junctions KU Leuven
Plasmonic devices, that exploit surface charge oscillations in metals, are well known for their ability to confine free-space light into extremely small nanoscale dimensions. They are widely regarded as a promising solution to overcome the size mismatch between optical and electrical components and open up avenues towards compact optical integrated circuits. If this mismatch could be solved, we can simultaneously benefit from the faster ...

Chiral semiconductor nanophotonics for ultraresolved molecular sensing Ghent University
Chirality plays a pivotal role in chemistry and medicine because most biological molecules have either right- or left-handed conformations. Circular dichroism can distinguish the chirality of matter thanks to a small difference in absorption of light with opposite circular polarizations. However, it is severely limited by low sensitivity and low spatial resolution due to weak chiral light-matter interaction. As a result, using light, we ...
PRIMO: an innovative platform to boost the development of microsystems in diagnostic, therapeutic and life science research applications KU Leuven
Tight control of the flow of light through CMOS compatible metasurfaces KU Leuven
Light can be shaped in different ways and forms by means of interference. When scaling down to the micro and nanoscale, light waves in confined nanostructures can present intriguing interference effects that give rise to exotic optical effects. These subwavelength (sub-λ) optical resonator and scatterers are dramatically expanding the toolset of the optical sciences and photonics engineering. By offering the opportunity to control and shape ...
