Abstract:Coherent frequency division of high-stability optical sources permits the extraction of microwave signals with ultralow phase noise, enabling their application to systems with stringent timing precision. To date, the highest performance systems have required tight phase stabilization of laboratory grade optical frequency combs to Fabry-Perot optical reference cavities for faithful optical-to-microwave frequency division. This requirement limits the technology to highlycontrolled laboratory environments. Here, … Show more
