Discover how frequency combs, specialized lasers with evenly spaced frequencies, enable precise light frequency comparison ...

A stable ‘frequency comb’ of photons with discrete colours has been generated on a microscale chip by removing copper contaminants from the circuit. The development of PICs was enabled by advances in ...

Researchers developed a new type of spectral shaper that can shape the spectrum of 10,000 lines of light from a laser frequency comb. The image shows the spatial light modulator they used with a 2D ...
