Understanding all-dielectric periodically modulated coatings for normal-incidence polarization control
Lina Grineviciute, Julianija Nikitina, Kestutis Staliunas
An ultracompact thin-film polarizer for normal-incidence (0° angle of incidence, AOI) applications is analytically and experimentally investigated. The device is based on Fano reso…
Nanoscale Surface Analysis of High Entropy Alloy
Hsin-Hui Huang, Meguya Ryu, Yoshiaki Nishijima +10
Nanoscale surface analysis of 1 micrometer thick high entropy alloys (HEAs) was carried out using nano-IR for hyperspectral imaging and single point spectroscopy in the 700-1700 1/…
Burst-mode fs-laser direct writing for full-thickness oxidation of Ta thin films
Lina Grineviciute, Hsin-Hui Huang, Haoran Mu +5
Direct fs-laser (1030~nm/200~fs) write of a throughout oxide TaO on a 200~nm Ta film was achieved using a combined ps- and ns- burst mode (Burst-in-Burst or BiB) of fs-…
Light Trapping by Non-Hermitian Thin Films
Lina Grineviciute, Ignas Lukosiunas, Julianija Nikitina +4
One of the exceptional features of non-Hermitian systems is the unidirectional wave interactions. Simultaneous modulation of the real and the imaginary part of the interaction pote…
Nanostructured Multilayer Coatings for Spatial Filtering
Lina Grineviciute, Ceren Babayigit, Darius Gailevičius +6
Spatial filtering is an important mechanism to improve the spatial quality of laser beams. Typically, a confocal arrangement of lenses with a diaphragm in the focal plane is used f…
