The dead time of a SPAD is a well known non-ideality within SPAD based systems. It encompases the short recharge time after a sucessful photon detection, when the device is fully insensitive to further photon events. 


In the literature, the dead time is often assumed to be fixed, although often with...

One cannot mount PCBs directly to the steel structure of the FLITES project. Apart from being poor industry practice, the PCBs arequite delicate. In combination with the other post-Doc on the project, Alex, we've needed to design suitable enclosured for the custom designed PCBs.

The FLITES project has required far more mechanical design that we originally envisaged. However with the help of some new staff at The University of Edinburgh, Edinburgh's superb mechanical technicians, Significant input from INTA in Madrid, Spain and out collegues at The University of Manchester,...

Single-Photon Avalanche Diodes (SPADs) in modern small dimension CMOS processes give a singular advantage for optical communications. With further development they allow the gain required in traditional optical recevers to be shifted away from electrical circuits and to be placed within the optical...
