A key building block for quantum photonics is represented by integrated detectors with high efficiency and timing resolution [1]. For high bandwidth quantum communication ultrafast detection is also needed. We realized extremely short superconducting nanowire detectors onto silicon nanophotonic platform which, thanks to their reduced kinetic inductance, can provide an extremely high detection rate [2]. To enhance their efficiency, we embedded these detectors into a two-dimensional photonic crystal cavity obtaining efficient and fast detectors with sub-ns recovery time.
