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…
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…
