Self-Tuning Transmitter for Quantum Key Distribution Using Machine Intelligence
Y. S. Lo, R. I. Woodward, T. Roger +5
The development and performance of quantum technologies heavily relies on the properties of the quantum states, which often require careful optimization of the driving conditions o…
Paving the Way towards 800 Gbps Quantum-Secured Optical Channel Deployment in Mission-Critical Environments
Marco Pistoia, Omar Amer, Monik R. Behera +16
This article describes experimental research studies conducted towards understanding the implementation aspects of high-capacity quantum-secured optical channels in mission-critica…
Advanced Laser Technology for Quantum Communications (Tutorial Review)
T. K. Paraïso, R. I. Woodward, D. G. Marangon +3
Quantum communications is the art of exchanging and manipulating information beyond the capabilities of the conventional technologies using the laws of quantum mechanics. With appl…
Real-time operation of a multi-rate, multi-protocol quantum key distribution transmitter
Innocenzo De Marco, Robert I. Woodward, George L. Roberts +6
Quantum key distribution (QKD) is the best candidate for securing communications against attackers, who may in the future exploit quantum-enhanced computational powers to break cla…
600 km repeater-like quantum communications with dual-band stabilisation
Mirko Pittaluga, Mariella Minder, Marco Lucamarini +5
Twin-field (TF) quantum key distribution (QKD) fundamentally alters the rate-distance relationship of QKD, offering the scaling of a single-node quantum repeater. Although recent e…
Dysprosium mid-infrared lasers: current status and future prospects
R. I. Woodward, M. R. Majewski, S. D. Jackson
With growing interest in the mid-infrared spectral region, dysprosium has recently been revisited for efficient high-performance infrared source development. Despite historically r…
Mode-locked and tunable fiber laser at the 3.5 m band using frequency-shifted feedback
Ori Henderson-Sapir, Nathaniel Bawden, Matthew R. Majewski +3
We report on a mid-infrared mode-locked fiber laser that uses an acousto-optic tunable filter to achieve frequency-shifted feedback pulse generation with frequency tuning over a 21…
Ultrafast mid-infrared fiber laser mode-locked using frequency-shifted feedback
M. R. Majewski, R. I. Woodward, S. D. Jackson
We demonstrate ultrashort pulse generation from a fluoride fiber laser co-doped with holmium and praseodymium. To date the majority of work focused on short pulse generation from t…
Q-switched Dy:ZBLAN fiber lasers beyond 3 μm: comparison of pulse generation using acousto-optic modulation and inkjet-printed black phosphorus
R. I. Woodward, M. R. Majewski, N. Macadam +4
We report high-energy mid-infrared pulse generation by Q-switching of dysprosium-doped fiber lasers for the first time. Two different modulation techniques are demonstrated. Firstl…
Mode-locked dysprosium fiber laser: picosecond pulse generation from 2.97 to 3.30 μm
R. I. Woodward, M. R. Majewski, S. D. Jackson
Mode-locked fiber laser technology to date has been limited to sub-3 μm wavelengths, despite significant application-driven demand for compact picosecond and femtosecond pulse sour…
Emission beyond 4 μm and mid-infrared lasing in a dysprosium-doped indium fluoride (InF3) fiber
M. R. Majewski, R. I. Woodward, J. -Y. Carreé +3
Optical emission from rare-earth-doped fluoride fibers has thus far been limited to less than 4 μm. We extend emission beyond this limit by employing an indium fluoride (InF3) glas…
Dysprosium-doped ZBLAN fiber laser tunable from 2.8 μm to 3.4 μm, pumped at 1.7 μm
M. R. Majewski, R. I. Woodward, S. D. Jackson
We demonstrate a mid-infrared dysprosium-doped fluoride fiber laser with a continuously tunable output range of 573 nm, pumped by a 1.7 μm Raman fiber laser. To the best of our kno…
Wideband saturable absorption in few-layer molybdenum diselenide (MoSe2) for Q-switching Yb-, Er- and Tm-doped fiber lasers
R. I. Woodward, R. C. T. Howe, T. H. Runcorn +4
We fabricate a free-standing molybdenum diselenide (MoSe2) saturable absorber by embedding liquid-phase exfoliated few-layer MoSe2 flakes into a polymer film. The MoSe2-polymer com…
