Plasmonic Nanolenses Produced by Cylindrical Vector Beam Printing for Sensing Applications
S. A. Syubaev, A. Yu. Zhizhchenko, D. V. Pavlov +8
Here, we demonstrate a simple direct maskless laser-based approach for fabrication of back-reflector-coupled plasmonic nanorings arrays. The approach is based on delicate ablation…
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…
Chemically non-perturbing SERS detection of catalytic reaction with black silicon
E. Mitsai, A. Kuchmizhak, E. Pustovalov +7
All-dielectric resonant micro- and nano-structures made of the high-index dielectrics recently emerge as a promising SERS platform which can complement or potentially replace the m…
Plasmon mode excitation and photoluminescence enhancement on silver nanoring
A. A. Kuchmizhak, S. O. Gurbatov, Yu. N. Kulchin +1
We demonstrate a simple and high-performance laser-assisted technique for silver nanoring fabrication, which includes the ablation of the Ag film by focused nanosecond pulses and s…
