Spatio-temporal characterization of the electric field of breathers in an optical fiber

Full experimental characterization of short pulses (with discrete line spectra) of the electric field (phase+intensity) in optical fibers is of high interest to get a detailed description of a large variety of nonlinear phenomena governed by the general nonlinear Schrödinger equation such as rogue wave formation or frequency comb generation. Recently, new techniques allowing real-time full-field characterization has been shown in the context of rogue waves [1] and laser dynamics [2]. However, experimental methods were limited so far to localized characterization of the field.
