Complex photonic superlattices via induced optical incremental multiplexing

In this contribution, we introduce a promising method to optically induce complex photonic superlattices. These multiperiodic structures have become an interesting field of research since exciting effects of light propagation in the linear as well as in the nonlinear regime like superlattice solitons and photonic analogies of Zitterbewegung as well as Klein tunnelling have been predicted theoretically. In general, the optical induction of photonic lattices is an auspicious approach for the creation of complex photonic refractive index gratings. Using lattice beams belonging to one of the four known nondiffracting beam families allows additionally the creation complex periodic, quasi- and even aperiodic curvilinear structures. These special intensity distributions are transferable even at low power to a corresponding refractive index change of a proper photorefractive material with the huge advantage of being reversible.
