Simulation of white light generation and near light bullets using a novel numerical technique

Adaptive Generation and Diagnostics of Linear Few-Cycle Light Bullets

Recently we introduced the class of highly localized wavepackets (HLWs) as a generalization of optical Bessel-like needle beams. Here we report on the progress in this field. In contrast to pulsed Bessel beams and Airy beams, ultrashort-pulsed HLWs propagate with high stability in both spatial and temporal domain, are nearly paraxial (supercollimated), have fringe-less spatial profiles and thus...

Chromatic effects near a white-light vortex

[12) Leach T.and Padgett M.J., 2003, New ]. Phys., 5 154 increased to make the largest of them fully saturated whilst maintaining their ratios. Figures 2 and 3 show our experimental results. Figure 2 contrasts the case where the optical vortices for each spectral component in the white-light source are overlapping and not overlapping. When the vortices are not overlapping, the chromascope image...

Generation of a White-Light Super Continuum

Light bullets in optical tandems.

We address the concept of three-dimensional light bullet formation in structures where nonlinearity and dispersion are contributed by different materials, including metamaterials, which are used at their best to create suitable conditions where bullets can form. The particular geometry considered here consists of alternating rings made of highly dispersive but weakly nonlinear media and strongl...

Stable discrete surface light bullets.

We analyze spatiotemporal light localization near the edge of a semi-infinite array of weakly coupled nonlinear optical waveguides and demonstrate the existence of a novel class of continuous-discrete spatiotemporal solitons, the so-called discrete surface light bullets. We show that their properties are strongly affected by the presence of the surface. To this end the crossover between surface...
