Abstract

The existence and properties of propagative nondispersive and nondiffracting localized envelope waves in dispersive transparent media, with either normal or anomalous group-velocity dispersion, showing subluminal group velocities and strong spatial localization are pointed out. Nonparaxial effects may lead to group-velocity reduction of several orders of magnitude. Numerical simulations are given for wave propagation in sapphire.
