Abstract:

We investigate the efficiency of a loop scheme for the spatial demultiplexing of N successive photons using only one Pockels cell at the center of the loop scheme. The maximum operating frequency of the Pockels cell, due to technical limitations, is 13.5 MHz. We experimentally find the maximum achievable demultiplexing efficiency with a single Pockels cell using continuous-wave and pulsed lasers and analog fast photodetectors. The maximum efficiency achieved at the maximum switching frequency is 87%.
