We discuss the observation of Vortex Light Bullets in Arrays of Waveguides. These are among the most complex spatiotemporal solitary waves observed in an experiment. They are characterized by a complex interplay of angular orbital momentum and nonlinear, spatiotemporal effects. We show that Vortex Light Bullets exhibit a new mode of stability and show that(More)
Glassy carbon is used nowadays for a variety of applications because of its mechanical strength, thermal stability and non-sticking adhesion properties. One application is glass molding that allows to realize high resolution diffractive optical elements on large areas and at affordable price appropriate for mass production. We study glassy carbon(More)
The work investigated compound entities, namely spatially bound LB complexes with angular momentum, called Vortex LBs (VLBs). An experimental excitation scheme using a discrete phase plate, generating a pump beam with the desired angular momentum, is discussed, while retaining the threefold symmetric field pattern with high field overlap with the desired(More)
