Relative Wavefront Error Correction Over a 2.4 km Free-Space Optical Link via Machine Learning
Nathan K. Long, Benjamin P. Dix-Matthews, Alex Frost +4
In coherent optical communication across turbulent atmospheric channels, reference beacons can be multiplexed with information-encoded signals during transmission. In this case, it…
Rapidly Tunable Synthetic Wavelength Ranging with an RFSoC
Shawn M. P. McSorley, Benjamin P. Dix-Matthews, Andrew M. Lance +2
Measurements of optical range and time-of-flight are crucial for a variety of high-precision technologies. Competitive optical measurement techniques have been developed that balan…
Commissioning of the TeraNet Optical Ground Station Network
Sascha Schediwy, Aliesha Aden, Benjamin Dix-Matthews +13
TeraNet is a new three-node OGS network that has been established in Western Australia. The network is built to support a broad range of space missions operating between LEO and th…
Super resolving binary-source hypothesis testing with a double-clad fiber coupler
John S. Wallis, David R. Gozzard, Alex M. Frost +3
We present a technique for binary spatial mode demultiplexing, using a double-clad fiber coupler as an optical mode sorter, for hypothesis testing for one or two point sources in a…
Phase stabilization for long baseline interferometry of incoherent optical sources
Joshua J. Collier, David R. Gozzard, John S. Wallis +1
The maximum baseline, and therefore resolution, of optical astronomical interferometers is limited by attenuation and phase noise within the optical path between the apertures and…
Uplink Pre-Compensation for Ground-to-Space Optical Communications Using Downlink Tomographic Reconstruction
Alex Frost, Nicolas Maron, Shane Walsh +3
Uplink pre-compensation in ground-to-satellite optical links remains a problem, with an appropriate measurement of the wavefront error in the uplink path often not being available.…
Quantum Wavefront Correction via Machine Learning for Satellite-to-Earth CV-QKD
Nathan K. Long, Ziqing Wang, Benjamin P. Dix-Matthews +4
State-of-the-art free-space continuous-variable quantum key distribution (CV-QKD) protocols use phase reference pulses to modulate the wavefront of a real local oscillator at the r…
Relative Wavefront Errors in Continuous-Variable Quantum Communication
Nathan K. Long, John Wallis, Alex Frost +4
When undertaking continuous-variable quantum key distribution (CV-QKD) across atmospheric channels, strong classical local oscillators (LOs) are often polarization-multiplexed with…
