Space-time wave packets (STWPs) constitute a broad class of pulsed optical fields that are
rigidly transported in linear media without diffraction or dispersion, and are therefore …

Spatial-and time-domain versions of the unidirectional pulse propagation equation (UPPE)
are derived and compared from the point of view of their practical application in simulations …

Needle beams are highly attractive for applications which take advantage from a spatial and
temporal localization of photons. High intensities, high resolution and extended depth of …

The peculiar spatiotemporal profile of an optical realization of the nonspreading
axisymmetric X wave has been recorded. For treatment of the experiment a simple …

The first article by Turunen and Friberg deals with a class of fields with propagation-invariant
properties such as the optical intensity distribution. Coherent and partially coherent …

A passive, matched two-time-derivative Lorentz material medium is designed to have its
equivalent permittivity and permeability smaller than their values in free space over a large …

In this paper we re-interpret a recently introduced method for obtaining non-separable,
localized solutions of homogeneous partial differential equations. This reinterpretation is in …

The Lorentz transformations of propagation-invariant localized waves (also known as
nondispersive or nondiffracting or undistorted progressive waves) are studied in the …

In this paper we extend for the case of Maxwell equations the “X-shaped” solutions
previously found in the case of scalar (eg, acoustic) wave equations. Such solutions are …

We propose a deterministic, measurement-free implementation of a cubic phase gate for
continuous-variable quantum information processing. In our scheme, the applications of …
