Special topic “Dielectric Nanoresonators and Metamaterials” of the Journal of Applied Physics open for submission until Dec. 31st

High-refractive-index (HRI) dielectric nanostructures, and in particular semiconductors, are attracting great attention in Optics and Photonics nowadays for their low dissipative losses, which hold promise of high-efficiency devices, and unique optical properties, exhibiting strong magnetic-like optical resonances and associated scattering directionality, which renders them as excellent nanoantennas. Thereby a wealth of new or enhanced fundamental…

Broadband optical response of graphene measured by terahertz time-domain spectroscopy and FTIR spectroscopy

In collaboration with the group of Prof. A. Bol, we have investigated the broadband optical response of graphene grown by chemical vapor deposition by combining terahertz time-domain spectroscopy (THz-TDS) at 0.25–1.7 THz with Fourier Transform Infrared Spectroscopy (FTIR) at 11–210 THz. These results have been published in the Journal of Applied Physics (J. Appl. Phys.124,…

Etendue reducers for free space optical communication

We propose a new technology based on optical nanoantennas for reducing the etendue (divergence) of light sources. This technology could be applied for long range optical communication. You can find more details in our recently accepted manuscript in ACS Photonics “Plasmonic Nanoantenna Arrays as Efficient Etendue Reducers for Optical Detection” or read the News item…

Congratulations to Ben Lont!

Ben Lont was a Fontys intern working on polariton lasing using plasmonic nanoantenna arrays. In his project he investigated guest-host complexes of polymers and dyes, to optimize the concentration of molecular emitters in the vicinity of plasmonic nanoparticle arrays. His thesis project “Polariton lasing using a highly doped dye-polymer complex as gain medium” was successfully defended at Fontys…

Article Publication: “Effect of optical damage resistant dopants on the dielectric properties of LiNbO3: Insight from broadband impedance spectroscopy and Raman scattering”

Lithium niobate is a widely used ferroelectric material with several interesting optical properties, however, it is prone to defect sites in the crystal which can lead to optical damage. To circumvent this, dopants can be incorporated into the crystal in a controlled manner, and in this work in collaboration with the Luxembourg Institute of Technology,…
