Creating nearly invisible wearable technologies such as smart contact lenses and ultrathin augmented reality (AR) glasses will require a radical redesign of conventional optical components. Instead of relying on bulky lenses and hardware, researchers are exploring materials that can manipulate light at the atomic scale.
A team from XPANCEO, working with scientists from the National University of Singapore and the University of Chemistry and Technology, Prague, has reported a major advance in that effort. Their study focuses on a layered crystal called molybdenum oxychloride (MoOCl2), which displays a collection of unusual optical properties that could help dramatically shrink future optical devices.
Published in Nano Letters, the research presents the first experimental mapping of the crystal's optical behavior. The findings show that MoOCl2 exhibits the strongest light-bending effect ever measured in a natural material, potentially opening a path toward much smaller and more capable optical technologies.
A Crystal That Acts Like Metal and Glass
Researchers describe MoOCl2 as a kind of optical "chameleon." Its behavior changes depending on how the crystal is oriented.
