Abstract

We present our progress in the development of an integrated technology suitable for the photonic quantum information processing, showing the first autocorrelator based on two separated detectors integrated on top of the same ridge waveguide. An efficiency of ∼1% at 1300 nm for both detectors and independent of the polarization of the incomingphotons, is reported. This ultracompact device enables the on-chip measurement of the second-order correlation function g(2)(τ). We will further discuss ongoing work on the integration of detectors with single-photon sources.
