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

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 ...

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 ...

…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 ...
