Nanostructured Organic Photonics

Light emitting organic materials, such as conjugated polymers and low-molar-mass compounds, exhibit appealing characteristics for the realization of active optical devices, including high luminescence efficiency, wide emission tunability, as well as simple and cheap processing. In particular, photonic crystals and their integration in planar and vertical microcavities based on organics provide an effective approach to control the light-matter interaction in solids, and to design and fabricate devices. Examples of applications which are here reviewed include distributed feedback lasers, nanopatterned organic light-emitting diodes and photonic crystal waveguides, and vertical architectures exploited in resonators, photodiodes, and microcavities showing strong exciton-photon coupling.
