NASA's new experimental antenna tracks deep space laser

An experimental antenna has received both radio frequency and near-infrared laser signals from NASA's Psyche spacecraft as it travels through deep space. This shows it's possible for the giant dish antennas of NASA's Deep ...

Submonolayer biolasers: Lower gain, higher sensitivity

Designing sensitive and single-use biosensors for early diagnosis remains a major challenge. Scientists in China have invented submonolayer lasers on optical fibers as ultrasensitive and disposable biosensors.

Distortion-free structured light

An exciting prospect in modern optics is to exploit patterns of light—how the light looks in its many degrees of freedom—often referred to as "structured light." Each distinct pattern could form an encoding alphabet for ...
