Scattering tomography of nanophotonic devices

ORAL

Abstract

We present a method for experimentally characterizing the multi-photon scattering matrix and multi-photon correlations from the output of complex nanophotonic devices. The tomography requires the preparation of coherent state pulses and the measurement of homodyne or intensity- intensity correlations. We explain the basic steps for the reconstruction of single- and two-photon processes, and provide a first experimental test using a quantum dot inside a photonic crystal waveguide. These results open the door to explore quantum light-matter interactions in the controlled multi-photon regime.
