Time-Frequency Transfer through a 70 dB Free Space Channel: Towards Satellite-Ground Time Dissemination
Qi Shen, Jian-Yu Guan, Ting Zeng +15
Time and frequency transfer lies at the heart of the field of metrology. Compared to current microwave dissemination such as GPS, optical domain dissemination can provide more than…
Steering optical comb frequency by rotating polarization state
Y. Zhang, L. Yan, X. F. Zhang +5
Optical frequency combs, with precise control of repetition rate and carrier-envelope-offset frequency, have revolutionized many fields, such as fine optical spectroscopy, optical…
Frequency and time transfer for metrology and beyond using telecommunication network fibres
Olivier Lopez, Fabien Kéfélian, Haifeng Jiang +11
The distribution and the comparison of an ultra-stable optical frequency and accurate time using optical fibres have been greatly improved in the last ten years. The frequency stab…
Analysis of shot noise in the detection of ultrashort optical pulse trains
Franklyn Quinlan, Tara M. Fortier, Haifeng Jiang +1
We present a frequency domain model of shot noise in the photodetection of ultrashort optical pulse trains using a time-varying analysis. Shot noise-limited photocurrent power spec…
Sub-femtosecond absolute timing precision with a 10 GHz hybrid photonic-microwave oscillator
T. M. Fortier, C. W. Nelson, A. Hati +10
We present an optical-electronic approach to generating microwave signals with high spectral purity. By circumventing shot noise and operating near fundamental thermal limits, we d…
Noise floor reduction of an Er:fiber laser-based photonic microwave generator
Haifeng Jiang, Jennifer Taylor, Franklyn Quinlan +2
The generation of microwaves from optical signals suffers from thermal and shot noise inherent in the photodetection process. This problem is more acute at lower pulse repetition r…
