Abstract

Optical two-way time and frequency transfer is an enabling technology that has applications ranging from fundamental investigations of relativity to the operation of global navigation satellite systems. While fiber frequency combs have demonstrated the most stable optical links, they are not ideal for applications that require very low SWaP-C. Here, we demonstrate two-way time and frequency transfer using electro-optic combs that have a direct path to full chip-scale integration. This two-way electro-optic time and frequency transfer system demonstrated instabilities as low as 15 fs at 1 s of averaging time. These results show a pathway to highly stable, agile and low SWaP-C time transfer networks.
