Consequences of non-differentiable angular dispersion in optics: tilted pulse fronts versus space-time wave packets [PDF]
Optics Express, 2022 Conventional diffractive and dispersive devices introduce angular dispersion (AD) into pulsed optical fields, thus producing so-called 'tilted pulse fronts'. Naturally, it is always assumed that the functional form of the wavelength-dependent propagation
