An international team of scientists led by researchers at the Peking University in China has designed a revolutionary ‘all-optical’ chip that uses light to synchronize the speed of processors and can ...

They’re consistently popular with the readers, which is admittedly part of my (and EDN’s) motivation to continue doing them. But I personally also find them fascinating; inevitably I come across at ...

Researchers at OSRAM Opto Semiconductors have succeeded in manufacturing high-performance blue and white LED prototypes in which the light-emitting gallium-nitride layers are grown on silicon wafers ...

Photonic quantum processors, devices that can process information leveraging quantum mechanical effects and particles of light (photons), have shown promise for numerous applications, ranging from ...

Integrated circuits are the brains behind modern electronic devices like computers or smart phones. Traditionally, these circuits—also known as chips—rely on electricity to process data. In recent ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2025.240159, discusses on-chip light control of semiconductor optoelectronic devices using integrated metasurfaces. Since the initial ...

In a leap toward practical quantum systems, researchers from Boston University, UC Berkeley, and Northwestern University have built the world’s first integrated electronic–photonic–quantum chip. The ...
