Laser polarization as a critical factor on the SERS-based molecular sensing performance of nano-gapped Au nanowires
Simón Roa, Terunori Kaihara, María Laura Pedano +2
Nowadays, Au dimer-based nanostructures are exhaustively studied due to their outstanding potential as plasmonic nanoantennas for future applications in high-sensitivity molecular…
Broadband tunable mid-infrared absorber based on conductive strip-like meta-atom elements
Henrik Parsamyan, Hovhannes Haroyan, Khachatur Nerkararyan
A metamaterial composed of thin metallic strips as an efficient broadband absorber in the mid-infrared spectrum is investigated. Here the matching between dielectric and geometrica…
Analysis of bistability at the coupling between waveguide and whispering gallery modes of a nonlinear hemicylinder
Henrik Parsamyan, Khachik Sahakyan, Khachatur Nerkararyan
The optical bistability caused by the coupling between modes of the parallel-plate waveguide and a nonlinear hemicylindrical crystal is studied using theoretical and numerical anal…
Efficient broadband infrared absorbers based on core-shell nanostructures
Henrik A. Parsamyan, Khachatur V. Nerkararyan, Sergey I. Bozhevolnyi
We suggest to exploit dielectric-metal core-shell nanostructures for efficient resonant and yet broadband absorption of infrared radiation with deeply subwavelength configurations.…
