Abstract
We investigate the propagation of femtosecond pulses in photonic lattices and the resulting excitation of Light Bullets, which are wavepackets that are self-confined in space and time by the nonlinearity. We employ an ultrafast cross-correlator to analyze the complex, spatiotemporal dynamics and characterize the Light Bullet’s unique evolution mechanism. Simulations with higher-order effects underline the solitary nature of the observed wavepackets and reveal a new decay mechanism that is generic for high-dimensional solitary waves.
