Ordered 'supercrystal' could make lasers faster, smaller and more efficient

A breakthrough from Monash University could pave the way for faster, smaller and more energy-efficient lasers and other light-based technologies. Engineers have developed a new type of perovskite material arranged into an ordered “supercrystal.” In this structure, tiny packets of energy called excitons work together rather than individually, allowing the material to amplify light much more efficiently. The findings, published in Laser & Photonics Reviews, could have applications in communications, sensors and computing, improving the performance of devices that rely on light, such as sensors in autonomous vehicles, medical imaging or electronics.
