    Polaritons in organic semiconductors are highly stable at room temperature, but so far nonlinear emission from these structures has not been demonstrated. Here, polariton lasing at room temperature in an organic microcavity composed of a melt-grown anthracene single crystal sandwiched between two dielectric mirrors is reported.

    Ferroelectrics may have a bright future for solar-energy generation, following the report that the domain walls of such materials can be engineered to exhibit a photovoltaic effect with an impressively high voltage output.

    The optical Kerr effect is a well-known phenomenon in which an electric field creates birefringence in a material. Researchers have now demonstrated this effect using single-cycle terahertz pulses — instead of optical pulses — in a variety of liquids.

    Active switching of plasmons by an external magnetic field is demonstrated in a metal–ferromagnet–metal structure. The strong modulation, combined with possible all-optical magnetization reversal induced by femtosecond light pulses, opens the door to ultrafast magneto-plasmonic switching.
