Light Synchronization Technique Heralds a Bright New Chapter for Small Atomic Clocks
In an effort to improve atomic clocks, JQI Fellow Kartik Srinivasan and his colleagues have been exploring how light is altered as it races repeatedly around a minuscule track on a chip. In an article in Nature, they describe a new way to use the devices to make precision measurements of light. The new technique might eliminate the need for several large, energy-hungry components in next-generation optical atomic clocks and other metrology tasks.
New publication on Dissipative Kerr Solitons in a III-V microresonator
Our paper, in collaboration with Prof. John Bowers' group from University of California at Santa Barbara, shows the generation of a Dissipative Kerr Soliton (DKS) in a III-V platform, namely AlGaAs-on-insulator, thanks to the quenching of the thermo-refractive effect at cryogenic temperaure.
