'Atomic photon source' based on the movement of atoms

Compact, CMOS compatible on-chip photon sources have attracted much attention to the scientific community and the semiconductor industry. As the transistor's feature size is continuously scaling down, the integration density ...

Printing optical chips as a layer cake

Faster, more energy-efficient ICT, or sensors to detect anything between beginning fruit rot and microscopic cracks in glass fibers: photonic technology holds great promises for the future. To deliver on those promises, a ...

A chip-scale microscope for high-throughput fluorescence imaging

Conventional light microscopy has been instrumental for studying cells and microorganisms; fluorescence microscopy enabled visualization of even smaller cell features by selectively adding fluorescent labels to molecules. ...

Tiny chip provides a big boost in precision optics

By merging two or more sources of light, interferometers create interference patterns that can provide remarkably detailed information about everything they illuminate, from a tiny flaw on a mirror, to the dispersion of pollutants ...

Millimeter-scale chip-based supercontinuum generation

In optics, when a collection of nonlinear processes act together on a pump beam, the resulting spectral broadening of the original pump beam gives rise to a supercontinuum. Supercontinuum sources for optical coherence tomography ...

New invention keeps qubits of light stable at room temperature

Researchers from University of Copenhagen have developed a new technique that keeps quantum bits of light stable at room temperature instead of only working at -270 degrees. Their discovery saves power and money and is a ...
