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.
Optical frequency combs emit a continuous train of short, closely spaced pulses of light containing millions of colors, which can be used to measure light waves as if they were radio waves. This allows technologies such as atomic clocks, computers and communications to be connected with optical waves that oscillate at 10,000 times higher frequencies than those found in electronics.
In the new work, researchers harness the newly proposed Kerr-induced synchronization of Kerr solitons to an external stable laser reference to produce optical frequency combs with higher levels of power. This creates a substantial increase of power on the other side of the comb spectrum from the reference laser.

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.
