Combining Two Established Systems to Create Something New

"Both meta-surfaces and light-switchable polymers have been known in principle for decades," explains Sarah Walden from the Institute of Solid State Physics, who now leads a research group in Australia. She adds, "but we are the first to combine both in this form to develop new components for optical applications." Meta-surfaces are nanostructured thin layers whose characteristic structural sizes are smaller than the wavelength of light. ...
