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

TL;DR

This paper demonstrates how structured PMMA films doped with Rhodamine B on silver can be used to control surface plasmon-coupled emission directionally through laser positioning and polarization, enabling deterministic azimuthal modulation.

Contribution

It introduces a method for azimuthally controlling directional SPCE using structured PMMA films and laser parameters, which was not previously demonstrated.

Findings

SPCE patterns can be modulated by laser position and polarization.

Structured PMMA films enable deterministic azimuthal control of SPCE.

The method allows for controlled directional emission in plasmonic systems.

Abstract

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.
