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.

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.
