Tilted-pulse-front pulses, which are produced via dispersive devices that introduce angular dispersion, are useful in many areas of nonlinear optics. Such pulses typically have large transverse cross sections and propagate for limited distances to offset the impact of diffractive space-time coupling that leads to spectral walk-off. Here we show that sculpting the spatiotemporal spectral profile of a pulsed plane wave enables the synthesis of propagation-invariant wave packets endowed with a tilted intensity pulse front with respect to the propagation axis. These wave packets are based on new elementary propagation-invariant wave packet solutions to the wave equation obtained by a complexification of the space and time degrees of freedom.
