A pressing quest in the field of nanoelectronics is the search for a material that could replace silicon. Graphene has seemed promising for decades. But its potential faltered along the way, due to damaging processing methods and the lack of a new electronics paradigm to embrace it. With silicon nearly maxed out in its ability to accommodate faster computing, the next big nanoelectronics platform is needed now more than ever.

New technology could aid in meeting the ever-growing need to move more data faster. Researchers have developed a new all-optical method for driving multiple highly dense nanolaser arrays. The approach could enable chip-based optical communication links that process and move data faster than today’s electronic-based devices.

“The development of optical interconnects equipped with high-density nanolasers would improve information processing in the data centers that move information across the internet,” sai...

A trio of researchers at Korea Advanced Institute of Science and Technology, working with a colleague at the University of Illinois at Urbana-Champaign, has designed and built a working quadruped robot with magnetized feet that can climb on the walls and ceilings of metal buildings and structures.

In their paper published in in the journal Science Robotics, Seungwoo Hong, Yong Um, Hae-Won Park and Jaejun Park describe their robot and how well it worked when tested under real world conditions.

As the technology used to build robots improves, engineers find more ways...

Research led by Monash University, RMIT and the University of Adelaide has developed an accurate method of controlling optical circuits on fingernail-sized photonic integrated circuits.

The development, published in the journal Optica builds on the work by the same team who recently created the world’s first self-calibrated photonic chip.

Photonics, or the use of light particles to store and transmit information, is a burgeoning field, supporting our need to create faster, better, more efficient and more sustainable technology.

Programmable photonic integrated circuits (PICs), offer diverse signal processing functions within a single chip, and present promising solutions for applications ranging from optical communications to artificial intelligence.

Whether it’s downloadi...
