Journal ArticleDOI
Hierarchical anti-reflective laser-induced periodic surface structures (LIPSSs) on amorphous Si films for sensing applications
Alexandr V. Dostovalov,Kirill Bronnikov,Victor P. Korolkov,S. A. Babin,Eugeny Mitsai,Alexander Mironenko,M. V. Tutov,Dongshi Zhang,Koji Sugioka,Jovan Maksimovic,Tomas Katkus,Saulius Juodkazis,Saulius Juodkazis,A. Zhizhchenko,Aleksandr A. Kuchmizhak +14 more
TL;DR: This work applied direct laser-induced periodic surface structuring to drive the phase transition of amorphous silicon into nanocrystalline Si imprinted as regular arrangement of Si nanopillars passivated with a SiO2 layer to form diverse hierarchical LIPSSs.
Journal ArticleDOI
Photoluminescence in hexagonal silicon carbide by direct femtosecond laser writing.
Stefania Castelletto,A. F. M. Almutairi,Kota Kumagai,Tomas Katkus,Yoshio Hayasaki,Brett C. Johnson,Saulius Juodkazis +6 more
TL;DR: Direct femtosecond laser writing has been used to produce localized regions of photo-luminescent emission in 4H- and 6H-silicon carbide and it is shown that the technique can produce specifically the silicon vacancy color center emitting in the range 850-950 nm and other emitters in the 700 nm.
Journal ArticleDOI
Single shot multispectral multidimensional imaging using chaotic waves.
Vijayakumar Anand,Soon Hock Ng,Jovan Maksimovic,Denver P. Linklater,Tomas Katkus,Elena P. Ivanova,Saulius Juodkazis,Saulius Juodkazis,Saulius Juodkazis +8 more
TL;DR: This study demonstrates a single camera shot, lensless, interferenceless, motionless, non-scanning, space, spectrum, and time resolved five-dimensional incoherent imaging technique using tailored chaotic waves with quasi-random intensity and phase distributions.
Journal ArticleDOI
Fresnel incoherent correlation holography with single camera shot
Anand Vijayakumar,Tomas Katkus,Stefan Lundgaard,Denver P. Linklater,Elena P. Ivanova,Soon Hock Ng,Saulius Juodkazis +6 more
TL;DR: In this paper, the authors used a randomly multiplexed bifocal binary diffractive Fresnel zone lenses fabricated using electron beam lithography for super-resolution 3D imaging.
Journal ArticleDOI
Single-shot mid-infrared incoherent holography using Lucy-Richardson-Rosen algorithm
Vijayakumar Anand,Molong Han,Jovan Maksimovic,Soon Hock Ng,Tomas Katkus,Annaleise R. Klein,Keith R. Bambery,Mark J. Tobin,Jitraporn Vongsvivut,Saulius Juodkazis +9 more
TL;DR: Lucy-Richardson-Rosen algorithm has been proposed in this article for 3D image reconstruction without two-beam interference (TBII) by using deterministic fields.
