Optical techniques enable us to examine single molecules, but do we really understand what we are seeing? After all, the fuzziness caused by effects such as light interference makes these images very difficult to interpret.

Researchers at the University of Twente's MESA+ research institute have developed a material capable of optical amplifications that are comparable to those achieved by the best, currently available semiconductor optical amplifiers. The researchers expect that this material will accelerate data communication and, ultimately, provide an alternative to short distance data communication (at the μm-cm scale).
