Dynamic control of Airy beam has been attracting scientists’ attention due to its potential applications in imaging, optical manipulation and laser manufacturing. However, traditional way of dynamic tuning of free space Airy beam usually requires bulky optics and will inevitably limit its practical applications. To solve this issue, a recent work proposes to use a compact meta-device which consists of two cascaded dielectric metasurfaces working in the visible regime.
