Optical frequency combs—laser sources that emit evenly spaced colors of light—are foundational, ubiquitous tools for precision measurement, found in optical clocks, gas-sensing spectrometers, and ...

Researchers have built a microscopic 3D-printed optical device that funnels light from 37 separate multimode semiconductor lasers into a single optical fiber, merging 222 distinct spatial modes; the ...

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 ...

Researchers have created a new photonic chip technology that guides light nearly as efficiently as optical fiber. By bringing fiber-like performance onto a silicon chip, they demonstrate that light ...

USI, a global leader in electronic design and manufacturing services, will participate in the Optical Fiber Communication Conference and Exhibition (OFC 2026) together with its subsidiary EugenLight ...

Light does a lot of work in the modern world, enabling all types of information technology, from TVs to satellites to fiber-optic cables that carry the internet across oceans. Stanford physicists ...

Researchers at the University of Adelaide, as part of an international team, have developed an approach that makes advanced microscopy possible through an optical fiber thinner than a human hair.

In a discovery that blurs the line between biology and technology, scientists have found that heart-shaped clams use fiber optic–like structures to channel sunlight through their shells in much the ...

Single-photon emitters quantum mechanically connect quantum bits (or qubits) between nodes in quantum networks. They are typically made by embedding rare-earth elements in optical fibers at extremely ...
