Dielectric geometric phase optical elements from femtosecond direct laser writing
Xuewen Wang, Aleksandr Kuchmizhak, Etienne Brasselet +1
We propose to use femtosecond direct laser writing technique to realize dielectric optical elements from photo-resist materials for the generation of structured light from purely g…
Laser printed nano-gratings: orientation and period peculiarities
Valdemar Stankevič, Gediminas Račiukaitis, Francesca Bragheri +4
Understanding of material behaviour at nanoscale under intense laser excitation is becoming critical for future application of nanotechnologies. Nanograting formation by linearly p…
Engineering and localization of quantum emitters in large hexagonal boron nitride layers
Sumin Choi, Toan Trong Tran, Christopher ElBadawi +6
Hexagonal boron nitride (hBN) is a wide bandgap van der Waals material that has recently emerged as promising platform for quantum photonics experiments. In this work we study the…
Percolation threshold gold films on columnar coatings: characterisation for SERS applications
Armandas Balcytis, Tomas Tolenis, Xuewen Wang +4
Percolation of gold films of ~15 nm thickness was controlled to achieve the largest openings during Au deposition. Gold was evaporated on 300-nm-thick films of nanostructured porou…
