Oxidation of Tantalum Nano-Film by Microwave Exposure
Massimiliano Zamengo, Lina Grineviciute, Hsin-Hui Huang +4
Oxidation and ablation of 200 nm tantalum films were carried out by three routes: (i) femtosecond (fs-)laser direct write, (ii) high-temperature annealing (HTA) in a tube furnace,…
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-…
3D Free-Form Optical Lens -- Miniaturised Fibre Couplers for Astrophotonics
Haoran Mu, Daniel Smith, Tomas Katkus +14
In astronomy, multi-object spectrographs employ fibre positioning robots to couple the light from multiple astronomy sources (stars or galaxies) into multiple multi-mode fibres, wh…
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…
Extremely Narrow, Sharp-Peaked Resonances at the Edge of the Continuum
Ignas Lukosiunas, Lina Grineviciute, Julianija Nikitina +2
We report a critical narrowing of resonances of a driven potential well, when their eigenfrequencies approach the edge of the continuum. The resonances also obtain unusual sharp-pe…
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…
Releasable micro-waveplates
L. Grineviciute, T. Tolenis, M. Ryu +7
A simple procedure is demonstrated for fabrication of waveplates which can be released from substrate by laser cutting. Oblique angle deposition, chemical etching and laser inscrip…
