Optical devices are critical in diverse military and civil applications, whereas traditional optical devices are bulky and heavy because they rely on the phase accumulation on a long optical path. In an article published in Science Advances, Prof. Xiangang Luo from the Chinese Academy of Sciences and co-workers have now demonstrated that ultrathin and lightweight optical devices could be constructed using nanostructures catenaries, which were typically used in architecture to construct incredible bridges and arches.
