Single Photon Imaging :Germanium on Silicon Single Photon Avalanche Detectors
QuantIC is developing a new single photon detection technology using germanium on silicon. The team combines the expertise for single photon detection
at Heriot Watt University with the micro- and nano- fabrication technology at the University of Glasgow to develop Ge on Si single photon avalanche detectors for operation at room temperature.
Initial results have demonstrated single photon detection and counting at 1.3 and 1.55 m wavelengths. The project is now optimising the technology for detectors that can operate from the visible to the eye- safe near-infrared parts of the electromagnetic spectrum (0.5 to 1.55 μm wavelengths).
Ge on Si single photon avalanche detectors offer potential key advantages over other technologies. The ability to fabricate large arrays using silicon foundries and integrate CMOS electronics can leverage the visible single photon technology already on the market. The technology being developed can also be integrated into silicon photonic circuits with applications in secure communications, ranging and healthcare.
Main application areas include:
• Quantum communications
• Astronomy
• Remote sensing
• Light detection and ranging (LIDAR)
• Medical and security imaging
QuantIC has a £4M Partnership Resource Fund to support industry led projects to develop our new technology and facilitate its translation to market. For more information, please contact:
