Brighter comb lasers on a chip mean new applications

Phys.org  August 29, 2023 While conventional optical frequency combs are generated using mode-locked lasers that tend to be constrained to high-end scientific laboratories, there has been recent work to develop optical frequency combs using compact, chip-scale microresonators based on dissipative Kerr solitons (DKSs) which consume very little energy, they also do not produce enough output power to be useful. A team of researchers in the US (NIST, University of Maryland) harnessed the newly proposed Kerr-induced synchronization of Kerr solitons to an external stable laser reference to produce optical frequency combs with substantial increase of power on the other side of […]
