RedWave Labs is excited to participate in Single Photon Workshop SPW 2026, taking place 6–10 July 2026 in Naples, Italy. The workshop brings together the global single-photon community to share the latest advances in quantum technologies, photonics, and precision optical measurements.
Visit us to discover our latest photon counting and time tagging systems, designed for applications requiring high timing accuracy, fast event processing, and reliable data acquisition. Our solutions support research in quantum optics, fluorescence lifetime measurements, photon correlation, optical sensing, spectroscopy, and detector characterization.
In addition to our exhibition, we are pleased to contribute to the scientific program with a presentation titled Redwave Labs: Precision electronics for quantum technologies, where we will discuss high-performance instrumentation and control systems for photonics and quantum applications: time taggers, photon counters, and control platforms for PNT, QKD, and quantum optics applications.
Meet our team to see live demonstrations, discuss your experimental challenges, and learn how RedWave Labs can help you achieve more accurate and efficient single-photon measurements.
We look forward to seeing you at SPW 2026!
A recent Journal of Lightwave Technology paper presents a full independent characterisation of our Single Photon Counter AD200 (Silicon), evaluating dark count rate, dead time, timing jitter, afterpulsing, and detection efficiency across multiple operating conditions
Importantly, the study benchmarks the AD200 against other commercially available Si-SPAD modules (Table I). The results show:
- Exceptionally low dark count rates (4–18 s⁻¹) — among the lowest reported
- >40% detection efficiency at 852 nm
- ~160–210 ps timing precision, comparable to or better than most competitors
- Large, uniform 500 µm active area

Table I: Comparison of the AD200 results with other commercially-available si-spads. detection efficiency values at 852 nm were estimated from wavelength response figures available in the referenced data sheets. for detectors with multiple sensor areas available, those closest in diameter to the sap500 are presented. https://ieeexplore.ieee.org/document/11304550
The paper concludes that the AD200 demonstrates state-of-the-art performance in dark count rate and timing precision, while maintaining strong efficiency – making it particularly attractive for quantum communications, metrology, and free-space photon detection.
Special thanks to the authors Luke Arabskyj, Liang Qiao, Dmitri Permogorov, Marco Lucamarini, and Christopher Chunnilall for their thorough and independent evaluation of the AD200.
