Diamond membranes: platform for photonic and opto-mechanical applications
Hsin-Hui Huang, Gediminas Seniutinas, Haoran Mu +8
Diamond 1 - 10 micrometers thick membranes are platform for photonic, quantum and opto-mechanic devices with applications across UV-IR spectral ranges. IR characterization of diamo…
Structure orientation determined in transmission and reflection: q-plate
Hsin-Hui Huang, Meguya Ryu, Shuji Kamegaki +9
Determination of orientation in the imaged sample/scene has a large application potential when the anisotropy of properties is analysed, usually, under a linearly polarised illumin…
Bessel-beam direct-write of the etch-mask in a nano-film of alumina for high-efficiency Si solar cells
Tomas Katkus, Soon Hock Ng, Haoran Mu +14
Large surface area applications such as high-efficiency > 26% solar cells require surface patterning with 1-10 micrometers periodic patterns at high fidelity over 1-10 cm^2 areas (…
Beyond Lambertian light trapping for large-area silicon solar cells: fabrication methods
Jovan Maksimovic, Jingwen Hu, Soon Hock Ng +7
Light trapping photonic crystal (PhC) patterns on the surface of Si solar cells provides a novel opportunity to approach the theoretical efficiency limit of 32.3%, for light-to-ele…
Hard X-ray Transient Grating Spectroscopy on Bismuth Germanate
Jeremy R. Rouxel, Danny Fainozzi, Roman Mankowsky +44
Optical-domain Transient Grating (TG) spectroscopy is a versatile background-free four-wave-mixing technique used to probe vibrational, magnetic and electronic degrees of freedom i…
All femtosecond optical pump and X-ray probe: holey-axicon for free electron laser
V. Anand, J. Maksimovic, T. Katkus +21
We put forward a co-axial pump(optical)-probe(X-rays) experimental concept and show performance of the optical component. A Bessel beam generator with a central 100 micrometers-dia…
Lithography-free Kirchhoff's Metasurfaces
Takuhiro Kumagai, Naoki To, Armandas Balcytis +3
Lithography-free metasurfaces composed of a nano-layered stack of materials are attractive not only due to their optical properties but also by virtue of fabrication simplicity and…
Kirchhoff's metasurfaces
Yoshiaki Nishijima, Armandas Balcytis, Shin Naganuma +2
Thermo-optical properties of the nanodisc and metal hole array plasmonic perfect absorber (PPA) metasurfaces were designed and characterised at midinfrared wavelengths. Both, light…
Single crystal diamond membranes containing germanium vacancy color centers
Kerem Bray, Blake Regan, Aleksandra Trycz +6
Single crystal diamond membranes that host optically active emitters are highly attractive components for integrated quantum nanophotonics. In this work we demonstrate bottom-up sy…
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…
