Metalenses are an emerging technology for controlling light that could someday replace traditional lenses. However, they generally lack dynamic control over their optical properties and are limited to passive optical applications. Researchers from the United States and Italy investigated infiltrating metalenses with liquid crystals to allow for dynamic control.

Metalenses, or flat surfaces that use nanostructures to focus light, are poised to revolutionize cameras, sensors, and displays—if the lenses can be mass produced. Researchers at the Harvard School of Engineering and Applied Sciences found deep-ultraviolet projection lithography can solve this production challenge.
