Researchers transformed red marker ink into graphene-based circuits using a laser, enabling low-cost, flexible electronics on everyday surfaces like paper or cups. (Nanowerk News) It is the first case ...

Silicon (Si) photonics has recently emerged as a key enabling technology in many application fields thanks to the mature Si process technology, the large silicon wafer size, and Si optical properties.

Engineers have led development of a laser-treatment process that allows them to use printed graphene for electric circuits and electrodes -- even on paper and other fragile surfaces. The technology ...

Many kinds of lasers are utilized in trapped-ion quantum technology. Conventional implementations of light sources are free-space optical circuits with many optical elements mounted on a rigid optical ...

Kirchhoff's current law has been rewritten thanks to a three-port transistor laser developed at the University of Illinois, US. While the laws of physics weren't made to be broken, sometimes they need ...

Chipmaker Intel believes that in the future, lasers could be used to develop extremely fast communications systems when integrated with silicon photonics. Most everyone is familiar with lasers in ...
