Antibunching measurements with InGaAs SPAD detectors are faced with the problems of high background count rate, afterpulsing, and the requirement to gate the SPADs. This application note describes how anti-bunching measurements can be performed by using pulsed excitation and gated detection. Possible problems of the principle are discussed and hints for the buildup of suitable experiments are given.
We describe picosecond time-resolved optical signal recording in the spectral range from 900 nm to 1700 nm. The system consists of an ID Quantique ID220 InGaAs SPAD, a bh SPC-150 TCSPC device, and a B&H BDS-SM 1064 nm ps diode laser.
The purpose of this application note is to compare secret key generation rates of our MDI-QKD system when being operated with standard ID200, and newer and more performant ID210 InGaAs-avalanche photodiode-based SPDs. When using the ID210 detectors, we find a fivefold increase in key rate for a distance of 60 km between users, and the possibility to distribute secret keys over longer distances.
