Since the Nobel Prize in Physics was awarded in 2005 for the invention of optical frequency combs, they have become a core technology in information systems. An optical frequency comb consists of a ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2025.240257 , discusses generation of avoided-mode-crossing soliton microcombs. Optical frequency combs refer to spectra composed of a ...

A team has developed an electro-optic frequency comb that is 100-times more efficient and has more than twice the bandwidth of previous state-of-the-art versions. On-chip laser frequency combs -- ...

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 ...

There are significantly different architectures for what are known as “atomic” clocks. Optically driven atomic clocks offer a new set of performance attributes. The optical atomic clocks use paired ...
