Arbitrary Pulse Shaping using Nonuniform Spacetime Modulation

This paper introduces and demonstrates a pulse shaping technique based on nonuniform spacetime modulation. This technique allows arbitrary pulse shaping and is in this regard unique, to the knowledge of the authors. Although we restrict here our attention to a 1+1D (1 dimension of time + 1 dimension of space) system, this idea can be extended to 1+2D (and 1+3D) systems, which will feature richer scattering phenomenology given the simultaneous transformations of the temporal vectorial spatial spectra of pulses.
