John Carmack has a habit of tossing out ideas that sit right on the edge between practical engineering and pure provocation. His latest musing lands squarely in that zone: what if a long loop of ...

Caltech scientists have developed a way to guide light on silicon wafers with low signal loss approaching that of optical fiber at visible wavelengths. This accomplishment paves the way for a new ...

As data traffic and computing demands continue to grow, photonic chips that process information with light instead of only with electrons are seen as a promising way to boost speed and energy ...

Optical fibers have become the foundation of modern data transmission, used for everything from telecoms and internet services to governmental and space applications. This is because they’re capable ...
