A large group of fiber optic lasers are powered by DC current. Laser drive is supplied by a current source with modulation added further along the signal path. The current source, although ...

A joint project led by Focused Energy, based in Darmstadt, Germany is developing what it calls "the world's first laser-driven neutron source for industrial use". The LDRS process (Laser-Driven ...

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 ...

Researchers at Trinity have developed a new light-based technology on a tiny chip that could help make the data centers ...

From 1970 to today, the clarity of fiber has continued to improve, becoming over 100 times clearer now and allowing networks to connect the world. For “groundbreaking achievements concerning the ...

Moving photonic ICs into the same package as silicon helps improve performance, but lasers remain outside. A new monolithic laser array allows hundreds of colors, each individually software-tunable ...

Telecommunications as an industry is often bogged down by technological inertia. Various regulations and dependencies mean that new innovations often don’t come to market for close to a decade, and ...

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 ...
