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 ...

Developing a flat soliton microcomb source

Optical chip-related technology is the inevitable path to retain the validity of Moore's Law, which has become the consensus of academia and industry; it can effectively solve the speed and power consumption problems of electronic ...

New method makes microcombs 10 times more efficient

Microcombs can help us discover planets outside our solar system and track new diseases in our bodies. But current microcombs are inefficient and unable to reach their full potential. Now, researchers at Chalmers University ...

Brighter comb lasers on a chip mean new applications

Researchers have shown that dissipative Kerr solitons (DKSs) can be used to create chip-based optical frequency combs with enough output power for use in optical atomic clocks and other practical applications. The advance ...
