Anisotropic surface plasmon-coupled emission from structured PMMA films doped with Rhodamine B

We report observation of anisotropic surface plasmon-coupled emission (SPCE) from structured PMMA films doped with Rhodamine B (RhB) and deposited on silver films. For a given structure, it is observed that relative position of incident laser spot to the structured PMMA and polarization properties of the laser beam can be used to modulate the SPCE patterns. The proposed method enables azimuthally controlling directional SPCE in a deterministic manner.

Excitation of surface plasmon polaritons guided mode by Rhodamine B molecules doped in PMMA stripe

In this letter we show the inclusion of Rhodamine B molecules (RhB) inside a dielectric-loaded surface plasmon waveguide enables for a precise determination of its optical characteristics. The principle relies on the coupling of the fluorescence emission of the dye to plasmonic waveguided modes allowed in of the structure. Using leakage radiation microscopy in real and reciprocal spaces, we measure the propagation constant of the mode and as well as their attenuation length.

Optical control of azo-polymer film loaded surface plasmon- polariton wave

An active control method of azo-polymer loaded surface plasmon-polaritons (SPPs) wave with tightly focused 532nm laser is proposed and demonstrated in this paper. Theoretical analysis and experimental results are consistent, which confirm the validity of this method. The optically active control method has the advantage of simple samples preparation, high spatial resolution and selectively control of the SPPs wave. This optical control of SPPs wave method has potential applications in integrated plasmonics.
