Om

Angelos joined NTNU as an Associate Professor of Optical Engineering and Nanophotonics in 2023. Prior to that he did his undergraduate and master degrees at the Department of Materials Science and Technology, University of Crete and obtained his PhD at the Optoelectronics Research Centre, University of Southampton. Then he was Research Fellow at the Cavendish Laboratory, University of Cambridge and Researcher at the Swiss Federal Laboratories for Materials Science and Technology.

 

Angelos serves as an Editorial Board Member of npj Nanophotonics part of Nature Portfolio and Early Career Editorial Advisory Board of APL Photonics.

Publikasjoner

Detecting mid-infrared light by molecular frequency upconversion in dual-wavelength nanoantennas. Science 374 (6572), 1268-1271

Here, for the first time, we used the infrared absorption and Raman activity of molecular vibrations in plasmonic nanocavities to demonstrate frequency upconversion.

Energy-resolved plasmonic chemistry in individual nanoreactors. Nature Nanotechnology 16 (12), 1378-1385

We have demonstrated an energy-resolved plasmonic tool that can be used to initiate and simultaneously spectroscopically probe chemical and physical processes at the surface of plasmonic nanostructures.

Interfering plasmons in coupled nanoresonators to boost light localization and SERS. Nano Letters 21 (6), 2512-2518

Plasmon interference in these hybrid microresonator nanocavities produces surface-enhanced Raman scattering (SERS) signals many-fold larger than in the bare plasmonic constructs.

Controlling optically driven atomic migration using crystal-facet control in plasmonic nanocavities. ACS Nano 14 (8), 10562-10568

We report a robust and simple technique to exploit crystal facets and their atomic boundaries to prevent the hopping of atoms along and between facet planes.

Fibre-optic metadevice for all-optical signal modulation based on coherent absorption. Nature Communications 9 (1), 182

We show that integration of metamaterial and optical fibre technologies allows the use of coherently controlled absorption in a fully fiberized and packaged switching metadevice

Nanoscale Metafoils with enhanced mechano-optical properties for solar radiation isolation. ACS Applied Nano Materials 5 (11), 16164-16171

Here, we show nanoscale “metafoils” with plasmon resonances, allowing interplay with visible radiation while reflecting the unwanted infrared responsible for device heating, essential for satellite applications.
