Researchers have shown that dissipative Kerr solitons (DKSs) can be used to create chip-based optical frequency combs with enough output power for use in optical atomic clocks and other practical applications. The advance could lead to chip-based instruments that can make precision measurements that were previously possible only in a few specialized laboratories.
Grégory Moille from the Joint Quantum Institute, NIST/University of Maryland, will present this research at Frontiers in Optics + Laser Science , which will be held 9–12 October 2023 at the Greater Tacoma Convention Center in Tacoma , Washington.
, but also reduces the power in each comb tooth. This makes it hard to interface on-chip combs with other system like atomic frequency standards. We show that by simply carefully injecting another weak laser in the comb device, it lets us tune the system and therefore optimize the power in several comb teeth power by more than an order of magnitude."

Researchers propose using pulsars to localize gravitational wave sourcesCurrent gravitational wave observatories have two significant limitations. The first is that they can only observe powerful gravitational bursts such as the mergers of black holes and neutron stars. The second is that they can only observe these mergers for wavelengths on the order of hundreds to thousands of kilometers. This means we can only observe stellar mass mergers. Of course, there's a lot of interesting gravitational astronomy going on at other wavelengths and noise levels, which has motivated astronomers to get clever. One of these clever ideas is to use pulsars as a telescope. Research has been published on the pre-print server arXiv.
