Tilted black-Si: ~0.45 form-birefringence from sub-wavelength needles
Darius Gailevicius, Meguya Ryu, Reo Honda +14
The self-organised conical needles produced by plasma etching of silicon (Si), known as black silicon (b-Si), create a form-birefringent surface texture when etching of Si orientat…
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…
Dielectric cross-shaped resonator based metasurface for vortex beam generation in Mid-IR and THz wavelengths
Raghu Dharmavarapu, Ken-ichi Izumi, Ikufumi Katayama +7
Metasurfaces are engineered thin surfaces comprising two dimensional (2D) arrays of sub-wavelength spaced and sub-wavelength sized resonators. Metasurfaces can locally manipulate t…
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…
Optical readout of hydrogen storage in films of Au and Pd
Yoshiaki Nishijima, Shogo Shimizu, Keisuke Kurihara +10
For hydrogen sensor and storage applications, films of Au and Pd were (i) co-sputtered at different rates or (ii) deposited in a sequential layer-by-layer fashion on a cover glass.…
Au-Ag-Cu nano-alloys: tailoring of permittivity
Yoshikazu Hashimoto, Gediminas Seniutinas, Armandas Balcytis +2
Precious metal alloys enables new possibilities to tailor materials for specific optical functions. Here we present a systematic study of the effects of a nanoscale alloying on the…
