Nonlinear X waves in second-harmonic generation: experimental results.

Physical review. E, Statistical, nonlinear, and soft matter physics

Jedrkiewicz O, Trull J, Valiulis G, Piskarskas A, Conti C, Trillo S, Di Trapani P.
PMID: 14525136
Phys Rev E Stat Nonlin Soft Matter Phys. 2003 Aug;68(2):026610. doi: 10.1103/PhysRevE.68.026610. Epub 2003 Aug 22.

X waves, spatiotemporal generalization of the monochromatic Bessel- (or Durnin-) type beams, are known in linear acoustic, microwave and optics for their unique property of defeating both spatial and temporal spreadings. Recently, we brought to the attention that X-type...

We numerically investigate the possibility to generate freely accelerating or decelerating pulses. In particular it is shown that acceleration along the propagation direction z may be obtained by a purely spatial modulation of an input Gaussian pulse in the...

Noise-seeded spatiotemporal modulation instability in normal dispersion.

In optical second-harmonic generation with normal dispersion, the virtually infinite bandwidth of the unbounded, hyperbolic, modulational instability leads to quenching of spatial multisoliton formation and to the occurrence of a catastrophic spatiotemporal breakup when an extended beam is left...

X entanglement: the nonfactorable spatiotemporal structure of biphoton correlation.

Physical review letters

Gatti A, Brambilla E, Caspani L, Jedrkiewicz O, Lugiato LA.
PMID: 19658864
Phys Rev Lett. 2009 Jun 05;102(22):223601. doi: 10.1103/PhysRevLett.102.223601. Epub 2009 Jun 04.

We investigate the spatiotemporal structure of the biphoton entanglement in parametric down-conversion (PDC) and we demonstrate its nonfactorable X-shaped geometry. Such a structure gives access to the ultrabroad bandwidth of PDC, and can be exploited to achieve a biphoton...

Nonlinear interactions are commonly used to access to wavelengths not covered by standard laser systems. In particular, optical parametric amplification (OPA) is a powerful technique to produce broadly tunable light. However, common implementations of OPA suffer from a well-known...
