Organic active photonic platforms for light confinement at the nanoscale

In this work, we show how J-aggregate doped polymers can establish a novel polymer organic active photonic platform for nanophotonics. These polymer materials are able to confine light at nanoscale supporting Surface Exciton Polaritons (SEP) similar to Surface Plasmon Polaritons. This novel organic platform can exploit the fabrication tools of supramolecular chemistry, to control and design J-aggregates which give access to light-confinement at desirable new wavelengths across the visible and near-infrared; extending plasmonics beyond the fixed properties of metals by a new means.
