The subject of our analysis are ultrafast multimode broadband twin-beam squeezed states generated via waveguided parametric downconversion. We utilize the rich spectral structure of the parametric downconversion process to generate an array of twin-beam squeezers into independent broadband spectral modes. Each of these distinct modes is readily available for broadband information coding.
