Optical rectification in a self-assembled monolayer containing nonlinear optical choromophore of hemicyanine adsorbed on a gold surface was observed in the attenuated total reflection geometry under the surface plasmon resonance condition. The effective second-order susceptibility χeff(2) was evaluated to be 43 pm V-1, which is consistent with the χ(2) values measured by linear electro-optic effect.

    Gradient metasurfaces (GMs) can provide pre-defined wave vectors that are along the surface of GMs. When the additional wave vector is greater than that of incident waves, the incident waves can be coupled efficiently as spoof plasmon polaritons (SPPs) even under normal incidence. In this...

    We have modeled, fabricated, and characterized a plasmonic metasurface with subwavelength features, whose dominant resonance is the independent of incident angle and polarization, and sensitive only to the material composition and geometry of a single element. Higher-order resonances, associated...

    We observe hybrid states of cavity photons and Tamm plasmons in an organic microcavity with an incorporated thin silver layer of increasing thickness up to 40 nm. Via μ-photoluminescence spectroscopy, we investigate their angular dependence. At oblique angles, we observe a TE-TM polarization...
