Description

Ultrastable Microwave System: photonic microwave technology representing a paradigm shift in microwave signal synthesis. This groundbreaking advancement is the first commercially-available photonic microwave source that utilizes the phase-coherent division of high-fidelity optical signals into the microwave domain. By employing this innovative approach, we can drastically reduce optical phase noise to levels that were previously physically impossible with more established technologies like multiplied OCXOs or room-temperature Sapphire oscillators.

The UMS-Compact is the bigger brother of the UMS-Mini. It also includes a fully autonomous ultrastable laser and a frequency comb, in a robust custom-designed rack-system to be operated in telecom cabinets, radar and radio-astronomy domes. It allows for the addition of customizable extensions for multiple frequency outputs, both in RF/Microwave or for comb-line synthesis at specific optical frequencies. The UMS-Compact can be further synchronized, on request, to optical or microwave signals as inputs, making it an ideal flywheel for metrological fiber networks and RF over fiber nodes. It is the follow-up system to the Menlo device featured in Jahangir et al.*.
