- Abstract: We present a single-pass source of broadband multimode squeezed light with
potential application in quantum information and quantum metrology. The source
is based on a type I parametric down-conversion (PDC) process inside a bulk
nonlinear crystal in a non-collinear configuration. The generated squeezed
light exhibits a spatiotemporal multimode behavior that is probed using a
homodyne measurement with a local oscillator shaped both spatially and
temporally. Finally we follow a covariance matrix based approach to reveal the
distribution of the squeezing among several independent temporal and spatial
modes. This unambiguously validates the multimode feature of our source.
