Two-dimensional defect modes in optically induced photonic lattices
Jiandong Wang, Jianke Yang, Zhigang Chen
In this article, localized linear defect modes due to bandgap guidance in two-dimensional photonic lattices with localized or non-localized defects are investigated theoretically.…
Defect modes in one-dimensional photonic lattices
Francesco Fedele, Jianke Yang, Zhigang Chen
Linear defect modes in one-dimensional photonic lattices are studied theoretically. For negative (repulsive) defects, various localized defect modes are found. The strongest confin…
Spontaneous Symmetry Breaking in Photonic Lattices: Theory and Experiment
P. G. Kevrekidis, Zhigang Chen, B. A. Malomed +2
We examine an example of spontaneous symmetry breaking in a double-well waveguide with a symmetric potential. The ground state of the system beyond a critical power becomes asymmet…
Observation of discrete vortex solitons in optically-induced photonic lattices
Dragomir N. Neshev, Tristram J. Alexander, Elena A. Ostrovskaya +4
We report on the frst experimental observation of discrete vortex solitons in two-dimensional optically-induced photonic lattices. We demonstrate strong stabilization of an optical…
Soliton stripes in two-dimensional nonlinear photonic lattices
Dragomir Neshev, Yuri S. Kivshar, Hector Martin +1
We study experimentally the interaction of a soliton with a nonlinear lattice. We observe the formation of a novel type of composite soliton created by strong coupling of mutually…
Discrete solitons and soliton-induced dislocations in partially-coherent photonic lattices
Hector Martin, Eugenia D. Eugenieva, Zhigang Chen +1
We investigate the interaction between a light beam and a two-dimensional photonic lattice that is photo-induced in a photorefractive crystal using partially coherent light. We dem…
