The additional degree of freedom as introduced by the orbital angular momentum (OAM) of light has revolutionized the various technological applications. Optical pulses with OAM have applications in the generation of twisted attosecond pulses, ultrafast spectroscopy, telecommunication, high harmonic generation and in many other areas of physics as well. In this paper, we present a numerical investigation of the propagation dynamics of ultrashort Laguerre Gauss (LG) vortices using nonlinear…

Couplings between the temporal and orbital angular momentum degrees of freedom in ultrafast optical vortices

In any form of wave propagation, strong spatiotemporal coupling appears when non-elementary, three-dimensional wave-packets are composed by superimposing pure plane waves, or spontaneously generated

Effect of Orbital Angular Momentum on Nondiffracting Ultrashort Optical Pulses.

The coupling between angular momentum and the temporal degrees of freedom of ultrashort pulses is discovered by generalizing the X-wave solution of the Maxwell equation and the spatial twist of propagation invariant light pulse turns out to be directly related to the number of optical cycles.

Upper Bound to the Orbital Angular Momentum Carried by an Ultrashort Pulse.

These limits have implications in experiments with ultrashort vortices, in the generation of twisted attosecond bursts in the extreme ultraviolet, the temporal resolution in ultrafast spectroscopy, or in the performance of OAM-based optical communications or cryptographic systems, as well as in other areas of physics as acoustics or electron waves.

Supertoroidal light pulses as electromagnetic skyrmions propagating in free space

Topological complex transient electromagnetic fields give access to nontrivial light-matter interactions and provide additional degrees of freedom for information transfer. An important example of

Measures of space-time nonseparability of electromagnetic pulses

Electromagnetic pulses are typically treated as space-time (or space-frequency) separable solutions of Maxwell's equations, where spatial and temporal (spectral) dependence can be treated separately.
