Efficiency improvement of high rate integrated time correlated single photon counting systems by incorporating an embedded FIFO

This work is dedicated to show the impact of integrating an embedded FIFO in a TCSPC system on the counting loss probability for a given expected arrival rate to an output rate frequency. To do this we used an M/D/1/N queuing model which is applied to design a multichannel TCSPC system. The results show that associating a FIFO to a multichannel system allows increasing the efficiency up to 90% while the standalone multichannel system one's is only of about 54%.
