Adelaide-based QuantX Labs plans to launch a key subsystem of its optical atomic clock into space to enhance position, navigation, and timing (PNT) capabilities.

in which each individual optical frequency component in the comb becomes an independent filter tap. They implemented a flat-top filter by applying positive and negative weights across 32 comb ...

In this project, we aimed to thoroughly utilize the excellent characteristics of "optical frequency combs" in broad areas of science and technology, thereby benefitting society as well. Therefore, as ...

“Mechanical frequency combs are poised to bring the applications and utility of optical frequency combs into the mechanical domain. So far, their main challenge has been strict requirements on drive ...

Since 2000, Diddams has been a research physicist at NIST, where he has pioneered the development of optical frequency combs and their use in optical clocks, tests of fundamental physics, novel ...
