Optical computing at sub-picosecond speeds

Vanderbilt researchers have developed the next generation of ultrafast data transmission that may make it possible to make already high-performance computing "on demand." The technology unjams bottlenecks in data streams ...

Plasma guides maintain focus of lasers

In science fiction, firing powerful lasers looks easy—the Death Star can just send destructive power hurtling through space as a tight beam. But in reality, once a powerful laser has been fired, care must be taken to ensure ...

Scientists grow optical chips in a petri dish

The modern photonics industry is constantly working on making its devices more compact, be it computing systems or sensors and lidars. For this, it is necessary to make lasers, transistors and other elements smaller. A team ...

Geometry of intricately fabricated glass makes light trap itself

Laser light traveling through ornately microfabricated glass has been shown to interact with itself to form self-sustaining wave patterns called solitons. The intricate design fabricated in the glass is a type of "photonic ...

New integrated device for nanometer-scale sensing

Researchers at Eindhoven University of Technology have developed a new, integrated optical sensor that provides increased resolution in measurements and paves the way for fully integrated and compact optical sensors including ...
