Lately, the optical research community has shown considerable interest in wave propagation phenomena in discrete structures.
Arrays or lattices of evanescently
coupled waveguides or chains of coupled microresonators are prime examples of structures where discrete optical wave dynamics can be observed. One question
that has naturally arisen is whether the Talbot effect is also possible in discrete systems.
