Dual-comb spectroscopy is an innovative optical technique that exploits pairs of laser frequency combs—light sources whose spectra consist of equidistant narrow lines—to facilitate high-resolution, ...

An improvement to a Nobel Prize-winning technology called a frequency comb enables it to measure light pulse arrival times with greater sensitivity than was previously possible — potentially improving ...

Optical frequency combs are specially designed lasers that act like rulers to accurately and rapidly measure specific frequencies of light. They can be used to detect and identify chemicals and ...

Conventional fluorescence microscopy provides poor quantitative information of the sample because it only captures fluorescence intensity, which changes frequently and depends on external factors. Now ...

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 ...

A frequency comb is a special kind of laser light whose spectrum, or set of frequencies, resembles the teeth of a comb. Instead of containing just one colour (one frequency), it emits a large number ...
