Abstract :
The integration of single-photon and photon-number-resolving detectors with single-photon sources and passive circuits is essential to realise fully-functional quantum photonic integrated circuits. We have recently demonstrated the first waveguide single photon detectors (WSPDs) [1] and a polarisation-independent on-chip autocorrelator for the measurement of the second-order correlation function g(2)(τ) [2], based on superconducting NbN nanowires on top of a GaAs/AlGaAs ridge waveguide.
