Time and frequency transfer plays an important role in the fields of navigation and positioning, remote sensing, and fundamental physics. The performance of long-haul frequency transfer is ultimately limited by accumulated phase and amplitude noise i

We explore the influence on the noise generated by photodetectors in the time-frequency transfer system. Choosing the input optical power within an appropriate range and the utilization of high-harmonic frequency can reduce the noise floor.

As an essential active device, electrical preamplifier has significant effect on frequency stability, which is extremely demanded by a frequency transfer system. In this work, we build an optical-comb based frequency transfer system and investigate t

We experimentally demonstrate a frequency transfer over 1000 km of fiber by exploiting the optical frequency comb. Through the feedback of the phase shifter, active phase noise cancellation is achieved. The fractional frequency instability of 2.4×10

Mixer is of crucial importance in evaluating the precision of the frequency transfer. We present preliminary results on the optimization of the practical mixer’s LO and RF input power parameters when performing downconversion. A fractional frequenc

Ultralight bosons such as axion-like particles are viable candidates for dark matter. They can form stable, macroscopic field configurations in the form of topological defects that could concentrate the dark matter density into many distinct, compact
