Abstract: 

 Recently, nonlinear light propagation in periodic photonic structures 
is attracting a lot of attention due to their novel physics as well as 
application potentials. In this talk, I will review recent work on 
nonlinear effects of light propagation in two-dimensional optically-induced
photonic lattices, such as the prediction and observation of fundamental 
lattice solitons. Then I will present our recent theoretical and 
experimental results on new types of soliton structures in photonic 
lattices such as vortex lattice solitons, dipole lattice solitons, and 
vector lattice solitons. This work was done in collaboration with Prof. 
Z. Chen at San Francisco State University.
