Abstract

Determining the modal structure of quantum light is important for photonic information processing, sensing, and imaging. A full modal characterization requires determining both the amplitude and phase of light’s spatial and spectral distributions, as well as its polarization. We propose using Hanbury Brown and Twiss “intensity interferometry” with a classical reference field to perform this full characterization without the need for phase stability or nonlinearities. The technique can be applied to any quantum signal, such as single photons and entangled photon pairs.
