Scientists have developed a mathematical model to explain how antiresonant hollow-core fibers guide light in a way that keeps data loss ultra-low. Until now, scientists had no complete explanation for ...

Researchers have developed a new optical sensor that provides a simple way to achieve real-time detection of extremely low levels of arsenic in water. Researchers have developed a new optical sensor ...

Schematic diagram and microscopic observation of an optical fiber doped with rare-earth atoms. The fluorescence from the entire optical fiber can be seen. (b) Schematic diagram and microscopic ...

Silica optical fibers exhibit intrinsic features such as ultralow loss, a high damage threshold, and a small mode field, enabling the possibility of long-haul communications and sensing, and have ...

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 ...

A colorful display of plastic optical fibers Commercial optical fibers generally carry light that’s invisible to the eye. The colorful ones shown here transmit visible light, demonstrating how fiber ...
