Crystalline metal flakes: Platforms for advanced plasmonics and hybrid 2D material architectures
Sergejs Boroviks, Siarhei Zavatski, Thorsten Feichtner +4
Crystalline noble metal flakes are emerging as versatile platforms in nanophotonics, enabling a broad range of optical phenomena and applications. Their atomically flat surfaces, h…
Two-Photon-Induced Direct 3D Printing of Freeform High-Index Phase-Change Sb2S3 Nanostructures
Abhrodeep Dey, Andrea Dellith, Anne Sauer +7
Chalcogenides have recently emerged as an important class of phase-change materials (PCMs) for nanophotonics, owing to their very high refractive index (RI) and low optical loss in…
Phase Matched Plasmonic Transmission Lines for Cascaded Second-Harmonic Generation as a Pathway to Nonlinear Logic Circuits
Komal Gupta, Anand Hegde, Xiaofei Wu +2
In nonlinear nanophotonics, cascaded second-harmonic generation (SHG) in pure plasmonic waveguides for sequential signal transformation and complex on-chip functionality remains a…
High-definition 3D suspended Archimedean spiral with broadband, spatially extended, and single-handed optical chirality enhancement in Vis-NIR range
Min Jiang, Abhik Chakraborty, Xiaofei Wu +2
3D plasmonic structures can provide giant optical chirality (C) in the near field, enabling strong interactions with enantiomers for chiral sensing applications. However, these str…
Positive-tone Nanolithography of Antimony Trisulfide with Femtosecond Laser Wet-etching
Abhrodeep Dey, Uwe Hübner, Albane Benardais +10
Antimony trisulfide (), as an emerging material for integrated photonic devices, has attracted significant attention due to its high index, low loss, and phase-changin…
