Researchers at Caltech have designed an approach for guiding light on silicon wafers with low signal loss comparable to that of optical fiber at visible wavelengths, which paves the way for a new generation of PICs.
Researchers are narrowing a decades-old performance gap between optical fiber and integrated photonics, which could fundamentally reshape photonic integrated circuits (PICs) and...
