Stability of Thin Film Refractory Plasmonic Materials Taken to High Temperatures in Air
Matthew P. Wells, Gomathi Gobalakrichenane, Ryan Bower +9
Materials such as W, TiN, and SrRuO3 (SRO) have been suggested as promising alternatives to Au and Ag in plasmonic applications owing to their refractory properties. However, inves…
Titanium oxynitride thin films with tunable double epsilon-near-zero behaviour
Laurentiu Braic, Nikolaos Vasilantonakis, Andrei P. Mihai +10
Titanium Oxynitride (TiOxNy) thin films are fabricated using reactive magnetron sputtering. The mechanism of their growth formation is explained and their optical properties are pr…
Influence of Photoexcitation Depth on Luminescence Spectra of Bulk GaAs Single Crystals and Defect Structure Characterization
V. A. Yuryev, V. P. Kalinushkin, A. V. Zayats +2
The results of investigation of bulk GaAs photoluminescence are presented taken from near-surface layers of different thicknesses using for excitation the light with the wavelength…
Far-field optical microscope with nanometer-scale resolution
Igor I. Smolyaninov, Christopher C. Davis, Jill Elliott +1
The resolution of far-field optical microscopes, which rely on propagating optical modes, is widely believed to be limited because of diffraction to a value on the order of a half-…
Broken Time Reversal of Light Interaction with Planar Chiral Nanostructures
A. S. Schwanecke, A. Krasavin, D. M. Bagnall +3
We report unambiguous experimental evidence of broken time reversal symmetry for the interaction of light with an artificial non-magnetic material. Polarized colour images of plana…
