An international research team has for the first time designed realistic photonic time crystals––exotic materials that exponentially amplify light. The breakthrough opens up exciting possibilities across fields such as communication, imaging and sensing by laying the foundations for faster and more compact lasers, sensors and other optical devices.
"This work could lead to the first experimental realization of photonic time crystals, propelling them into practical applications and potentially transforming industries. From high-efficiency light amplifiers and advanced sensors to innovative laser technologies, this research challenges the boundaries of how we can control the light-matter interaction," says Assistant Professor Viktar Asadchy from Aalto University, Finland.
The study is published in the journal Nature Photonics.
