Shaping caustics into propagation-invariant light
Alessandro Zannotti, Cornelia Denz, Miguel A. Alonso +1
Structured light has revolutionized optical particle manipulation and nano-scale material processing. In particular, propagation-invariant structured light fields, such as Bessel b…
Dynamics of the optical swallowtail catastrophe
Alessandro Zannotti, Falko Diebel, Cornelia Denz
Perturbing the external control parameters of nonlinear systems leads to dramatic changes of its bifurcations. A branch of singular theory, the catastrophe theory, analyses the gen…
Pearcey solitons in curved nonlinear photonic caustic lattices
Alessandro Zannotti, Matthias Rüschenbaum, Cornelia Denz
Controlling artificial Pearcey and swallowtail beams allows realizing caustic lattices in nonlinear photosensitive media at very low light intensities. We examine their functionali…
Optical catastrophes of the swallowtail and butterfly beams
Alessandro Zannotti, Falko Diebel, Martin Boguslawski +1
We experimentally realize higher-order catastrophic structures in light fields to access the rich class of caustic swallowtail and butterfly beams. These beams present solutions of…
