Photonic chip-based low noise microwave oscillator
Igor Kudelin, William Groman, Qing-Xin Ji +26
Numerous modern technologies are reliant on the low-phase noise and exquisite timing stability of microwave signals. Substantial progress has been made in the field of microwave ph…
Thermal-noise-limited, compact optical reference cavity operated without a vacuum enclosure
Yifan Liu, Charles A. McLemore, Megan Kelleher +7
We present an in-vacuum bonded, 9.7 mL-volume Fabry-Pérot ultrastable optical reference cavity that operates without a vacuum enclosure. A laser stabilized to the cavity demonstrat…
Advanced Distributed Submarine Cable Monitoring and Environmental Sensing using Constant Power Probe Signals and Coherent Detection
Mikael Mazur, Nicolas K. Fontaine, Megan Kelleher +6
In this work we demonstrate an FPGA-based coherent optical frequency domain reflectometry setup for cable monitoring. Using coherent detection for averaging and narrowband filterin…
The photodetection of ultrashort optical pulse trains for low noise microwave signal generation
Franklyn Quinlan
Electrical signals derived from optical sources have achieved record-low levels of phase noise, and have demonstrated the highest frequency stability yet achieved in the microwave…
Compact, Portable, Thermal-Noise-Limited Optical Cavity with Low Acceleration Sensitivity
Megan Lauree Kelleher, Charles A. McLemore, Dahyeon Lee +3
We develop and demonstrate a compact (less than mL) portable Fabry-Pérot optical reference cavity. A laser locked to the cavity is thermal noise limited at fr…
