Impact of Plasmonic Modes and Thermophysical Properties on the Double-Pulse Structuring of Highly-Ordered LIPSS for Biosensing Applications
G. D. Tsibidis, F. Fraggelakis, P. Lingos +5
The fabrication of highly ordered laser-induced periodic surface structures (LIPSS) on thin metallic films is dictated, predomaninatly, by a synergy of periodic electromagnetic ene…
Non-polaritonic effects in cavity-modified photochemistry
Philip A. Thomas, Wai Jue Tan, Vasyl G. Kravets +2
Strong coupling of molecules to vacuum fields has been widely reported to lead to modified chemical properties such as reaction rates. However, some recent attempts to reproduce in…
Highly ordered LIPSS on Au thin film for plasmonic sensing fabricated by double femtosecond pulses
Fotis Fraggelakis, Panagiotis Lingos, George D. Tsibidis +7
Periodic plasmonic arrays making possible excitations of surface lattice resonances (SLRs) or quasi-resonant features are of great importance for biosensing and other applications.…
Topological phase singularities in atomically thin high-refractive-index materials
Georgy Ermolaev, Kirill Voronin, Denis G. Baranov +15
Atomically thin transition metal dichalcogenides (TMDCs) present a promising platform for numerous photonic applications due to excitonic spectral features, possibility to tune the…
Two-dimensional covalent crystals by chemical conversion of thin van der Waals materials
Vishnu Sreepal, Mehmet Yagmurcukardes, Kalangi S. Vasu +14
Most of the studied two-dimensional (2D) materials have been obtained by exfoliation of van der Waals crystals. Recently, there has been growing interest in fabricating synthetic 2…
Direct retrieval method of the effective permittivity and permeability of bulk semi-infinite metamaterials by variable-angle spectroscopic ellipsometry
Quentin Flamant, Daniel Torrent, Sergio Gomez-Graña +5
In this work, we present a simple method for the direct retrieval of the effective permittivity and permeability of a bulk semi-infinite metamaterial from variable-angle spectrosco…
