Photonics concerns the generation, transport, processing and detection of light. It underlies a large amount of industrial activity, mainly devoted to information technology, telecommunications, environmental monitoring, biomedical science and instrumentation.

The field has received a powerful impetus recently with the introduction of nanoscale concepts. Moreover, organic materials now appear as key components in photonic devices such as light-emitting diodes, integrated lasers, or photovoltaic cells. Organic molecular systems offer unique opportunities in nanophotonics since both...
