Abstract

We present a characterisation technique for a photonic-Iantern-based spatial-division mul-tiplexed link using temporally-resolved coincidence measurements of SPDC photon pairs. Differential modal delay and input path imbalance allow unambiguous identification of spatial mode propagation and coupling errors, providing information that can be used for link optimization.
