Observation of nonlinear self-trapping in triangular photonic lattices

Rosberg, Christian R.; Neshev, Dragomir N.; Sukhorukov, Andrey A.; Krolikowski, Wieslaw; Kivshar, Yuri S.


We experimentally study light self-trapping in triangular photonic lattices induced optically in nonlinear photorefractive crystals. We observe the formation of two-dimensional discrete and gap spatial solitons originating from the first and second bands of the linear transmission spectrum.
