Metalens Uses Heat, Not Motion, to Shift Focus
A new metalens design developed by researchers at MIT, which is able to change its focus without tilting or moving forward or backward, may find use in miniature heat scopes for drones, ultracompact thermal cameras for cellphones, and low-profile night-vision goggles, its developers said. The lens technology uses heat to focus in on different objects, operating in the infrared band.

Optical Angular Momentum Shatters Data Ceiling
An optical antenna developed by researchers at the University of California, Berkeley, can, in principle, provide limitless bandwidth. The technology takes advantage of orbital angular momentum (OAM), a characteristic of light that enables multiplexing, or simultaneous transmission, exponentially greater than current technology.
