  • Thin film interference is integral to modern photonics; however, it inevitably leads to an undesired change of spectral characteristics with angle. Here, the authors overcome this fundamental limit by utilizing and tuning exciton-polaritons arising in ultra-strongly coupled microcavities.

  • The addition of a strong coupling layer allows polariton-based emission from red and green organic light-emitting diodes with high external quantum efficiency up to 10%, linewidth smaller than 20 nm and angle-independent emission, with spectral shifts smaller than 10 nm over a 60° angular tilt.

  • Organic exciton-polaritons represent an attractive platform for quantum devices. Here, authors show how introducing Schlieren texturing and a rough intra-cavity topography in a liquid crystalline polymer enables strong in-plane confinement of polaritons and drastically improved lasing.

  • Interfaces of organic donor-acceptor blends provide intermolecular charge-transfer states with red-shifted but weak absorption. By introducing an optical micro-cavity; Siegmundet al., enhance their photoresponse to achieve narrowband NIR photodetection with broad spectral tunability.

  • The understanding of the orientation of luminescent molecules is currently limited by the ensemble-averaging nature of state-of-the-art measurements. Here, the authors apply single-molecule imaging to obtain complete orientation distributions of the transition dipole of individual emitter molecules.

  • Strong light-matter coupling can tune exciton properties but its effect in photovoltaics remains unexplored. Here Nikolis et al. show that the photon energy loss from optical gap to open-circuit voltage can be reduced to unprecedented values by embedding organic solar cells in optical microcavities.

  • Though organic light-emitting diodes (OLEDs) with impressive flexibility have been reported, achieving stable operation in air and moist environments remains difficult. Here, the authors report ultrathin OLEDs with hybrid thin-film encapsulation barriers for stable operation in harsh environments.
