On the reduction of gas permeation through the glass windows of micromachined vapor cells using AlO coatings

Clément Carlé, Andrei Mursa, Petri Karvinen +5

Stability and precision of atomic devices are closely tied to the quality and stability of the internal atmosphere of the atomic vapor cells on which they rely. Such atmosphere can…

Reduction of helium permeation in microfabricated cells using aluminosilicate glass substrates and AlO coatings

C. Carlé, S. Keshavarzi, A. Mursa +10

The stability and accuracy of atomic devices can be degraded by the evolution of their cell inner atmosphere. Hence, the undesired entrance or leakage of background or buffer gas,…

High-Q guided-mode resonance of a crossed grating with near-flat dispersion

Reuben Amedalor, Petri Karvinen, Henri Pesonen +3

Guided-mode resonances in diffraction gratings are manifested as peaks (dips) in reflection (transmission) spectra. Smaller resonance line widths (higher Q-factors) ensure stronger…

Thermal Control of Plasmonic Surface Lattice Resonances

Jussi Kelavuori, Viatcheslav Vanyukov, Timo Stolt +4

Plasmonic metasurfaces exhibiting collective responses known as surface lattice resonances (SLRs) show potential for realizing tunable and flat photonic components for wavelength-s…

Multiply-resonant Second-harmonic Generation using Surface Lattice Resonances in Aluminum Metasurfaces

Timo Stolt, Anna Vesala, Heikki Rekola +3

Nonlinear metamaterials show potential for realizing flat nonlinear optical devices but generally lack in terms of achievable conversion efficiencies. Recent work has focused on en…

Fabrication of diamond diffraction gratings for experiments with intense hard x-rays

Mikako Makita, Petri Karvinen, Vitaliy A. Guzenko +3

The demands on optical components to tolerate high radiation dose and manipulate hard x-ray beams that can fit the experiment requirements, are constantly increasing due to the adv…
