SPEXS is a collaboration of research teams across four universities, led by Professor Gerald Buller of Heriot Watt University, working in partnership with seventeen commercial and governmental organisations and funded by EPSRC.  The project’s aim is to address one of the key aspects of single-photon detection – that of increasing the wavelength region of detection into the Short-Wave/Mid-Wave Infrared to enhance a range of rapidly emerging applications, for example in quantum technology, automotive lidar and bio-photonics.  The complementary expertise of the partners will be harnessed to provide solutions for a range of key future sensing requirements.
