Caltech scientists have developed a way to guide light on silicon wafers with low signal loss approaching that of optical ...

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 the Wellman Center for Photomedicine have demonstrated that wavelength-dependent changes in the spatial distribution of light transmitted through a multimode optical fiber are not ...

Quantum computing has long promised to crack problems that defeat even the fastest supercomputers, but the hardware has ...

- Development of the world's first practical surface-emitting laser suitable for optical fiber communications systems. - Utilization of quantum dots as an optical gain medium, enabled by NICT's ...

Researchers at the University of California, Santa Cruz, have reported the first demonstration of integrated optical waveguides with liquid cores, a technology that enables light propagation through ...

Patients who remain in bed for long periods of time may develop pressure sores, which can in turn become potentially life-threatening chronic skin ulcers. A new sensor could help keep that from ...

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 ...
