Light powers everything from communications to sensing, yet even tiny imperfections can scatter it and weaken signals. To address this, a team led by the University of Bath—working with the University ...

A joint initiative by Chinese researchers and engineers has set a new record for real-time fiber-optic communications. The ...

Scientists have been presenting evidence that the Earth is round for well over 2,000 years. Yet flat-Earthers remain unconvinced, with some willing to go to the end of the Earth to prove their point.

Caltech scientists have created ultra-low-loss optical pathways on silicon chips that approach the efficiency of fiber optics and dramatically outperform existing technology at visible wavelengths.
