Title: Self imaging from fractional Gouy phases in paraxial optics.

Abstract: We investigate self-imaging structures composed by paraxial
mode superpositions
in optics. When different mode orders are combined, the resulting
pattern is not preserved
under free propagation and gets transformed as a result of non
synchronized Gouy phases.
However, it is possible to build self imaging structures in which the
Gouy phases synchronize
at specific longitudinal positions,
recovering the initial pattern.
