The creative new approach could lead to more energy-efficient machine-learning hardware. On a table in his lab at the University of Pennsylvania, physicist Sam Dillavou has connected an array of ...

Researchers at Kyushu University have designed a class of molecules whose ability to amplify light energy can be actively ...

Physicists propose a novel way to create photoconductive circuits, where the circuit is directly patterned onto a glass surface with femtosecond laser light. The new technology may one day be useful ...

This file type includes high resolution graphics and schematics when applicable. A most critical device in an optical networking system is the laser diode, since it’s responsible for converting the ...
