Hybrid plasmonics relies on radiative and non-radiative coupling between Metal Nano Particles (MNP) and other (often organic) materials. It is at the origin of recent development of active plasmonics and “Spasers” (Surface Plasmons Amplification by Stimulated Emission of Radiation). Hybrid nanosystems are generally fabricated from isotropic coating of MNP using a homogeneous optically active dielectric material. Such isotropy prevents the selection of any specific emission mode of the hybrid particle using the incident light polarization.

The HAPPLE project aims at developing an original approach for the realization of new light-emitting hybrid metal/polymer nano-systems (LEHPS) presenting an anisotropic spatial distribution of organic active medium. As a result, modes and optical properties of LEPHS can be selectively activated with the polarization state of the incident light.

LEHPS fabrication is based on a near-field photopolymerization process triggered by plasmon-enhanced fields produced by the MNP itself. The result is a MNP exhibiting a polymeric coating reproducing the excited optical near-field intensity distribution.
