Diffraction limited focusing and routing of gap plasmons by a metal-dielectric-metal lens
Brian S. Dennis, David A. Czaplewski, Michael I. Haftel +3
Passive optical elements can play key roles in photonic applications such as plasmonic integrated circuits. Here we experimentally demonstrate passive gap-plasmon focusing and rout…
Ultracompact Nano-Mechanical Plasmonic Phase Modulators
Brian S. Dennis, Michael I. Haftel, David A. Czaplewski +3
Dielectrics' refractive index limits photonics miniaturization. By coupling light to metal's free electrons, plasmonic devices achieve deeper localization, which scales with the de…
Sliding Density-Wave in Sr_{14}Cu_{24}O_{41} Ladder Compounds
G. Blumberg, P. Littlewood, A. Gozar +4
We used transport and Raman scattering measurements to identify the insulating state of self-doped spin 1/2 two-leg ladders of Sr_{14}Cu_{24}O_{41} as a weakly pinned, sliding dens…
Collective density wave excitations in two-leg Sr_{14-x}Ca_xCu_{24}O_{41} ladders
A. Gozar, G. Blumberg, P. B. Littlewood +4
Raman measurements in the 1.5 - 20 cm-1 energy range were performed on single crystals of Sr_{14-x}Ca_xCu_{24}O_{41}. A quasielastic scattering peak (QEP) which softens with coolin…
Spin dynamics of Sr_14Cu_24O_41 two-leg ladder studied by Raman spectroscopy
A. Gozar, G. Blumberg, B. S. Dennis +4
The two-magnon (2M) excitation at 3000 cm-1 in Sr_14Cu_24O_41 two-leg ladder is studied by Raman scattering. A slight anisotropy of the superexchange coupling J_{\perp}/J_{||} \app…
