There is demand for quantum sensors that are capable of parallelised time-resolved single photon counting (TCSPC) to enhance efficiency and speed. However, various applications require different area, line, and array sensor architectures. In line with the quantum enhanced/single photon imaging scope of this call, we will develop demonstrator prototypes of a fibre/s-fed, low noise, 1024-fold parallelised TCSPC detector array. We will explore areas where this product can become a key enabling technology for applications identified in the UK Quantum Roadmap, including surveillance, LIDAR, microscopy, medical imaging, spectroscopy etc. We will innovatively combine a prototype TCSPC array with novel optical coupling technologies, efficiently distributing light from either a single multimode fibre, or an array of single-mode fibres, to the sensor pixels.Through this project, Photon Force will advance its product portfolio leading to a future range of fully integrated TCSPC products that are immediately suitable for new markets. The developed integrated optical coupling technologies will allow us to respond rapidly to emerging demands for new quantum imaging sensors, and will have a role to play in wider quantum metrology, sensing, information and science. Heriot Watt and Fraunhofer UK will benefit from early access to state-of-the-art quantum image sensors. Heriot Watt has a critical mass of world-leading research in single-photon science, with a particular focus on first-photon imaging, for applications ranging from ballistic imaging of medical instruments, to imaging light-in-flight.
