High-quality microwave signals generated from tiny photonic chip

In a new Nature study, Columbia Engineering researchers have built a photonic chip that is able to produce high-quality, ultra-low-noise microwave signals using only a single laser. The compact device—a chip so small, it ...

Printing optical chips as a layer cake

Faster, more energy-efficient ICT, or sensors to detect anything between beginning fruit rot and microscopic cracks in glass fibers: photonic technology holds great promises for the future. To deliver on those promises, a ...

Photonics: Enabling next-generation wireless networks

Wireless transmission at microwave frequencies is important for high-data-rate transmission applications, such as mobile phone networks, satellite links and remote imaging. Now, Xianshu Luo and colleagues from the A*STAR ...

UPNA researchers develop an ultra-low consumption chip

Researchers at the NUP/UPNA-Public University of Navarre have developed a chip incorporating a new design of ultra-low consumption, digital analogue converter; it consumes 50 million times less than a conventional light bulb. ...

New micro water sensor can aid growers

(Phys.org) —Crop growers, wine grape and other fruit growers, food processors and even concrete makers all benefit from water sensors for accurate, steady and numerous moisture readings. But current sensors are large, may ...
