Optical frequency combs—laser sources that emit evenly spaced colors of light—are foundational, ubiquitous tools for ...

A new theoretical study suggests that gravitational waves may leave subtle signatures not in giant detectors, but in the light emitted by atoms.

A frequency comb is a spectrum of evenly spaced, phase-coherent laser lines, that acts like a ruler to measure the frequency of light with extreme precision. The dual-comb technique does not suffer ...

For high-speed and large-capacity optical communication applications and improvement of accuracy in microwave generation and evaluation equipment Results: NTT and their partners have developed a ...

…and Stanford launches “micro” frequency comb, as basis for mass-market adoption of such devices. An ultraviolet photon-counting dual-comb spectrometer. Scientists in the group of Nathalie Picqué at ...

A tiny metasurface chip can turn invisible infrared light into steerable visible beams, opening the door to powerful new ...

An international team led by researchers at Penn State and Université Paris-Saclay has gained precise control over light emitted from nanoscale sources embedded in two-dimensional (2D) materials. This ...
