Mathematical Study of Light Propagation in Optically-induced Photonic Lattices

Abstract:  Recently, light propagation in optically-induced photonic lattices is attracting a lot of attention in the optics community due to its potential applications to micro-scale optical devices. These photonic lattices induce a periodic refractive-index variation and are akin to photonic crystals. But since these lattices are created optically, they are very easy to control and manipulate. Also, the nonlinearity in these lattices can be very strong in a photorefractive crystal. 

In this talk, I will give an overview of this subject, and report our recent mathematical studies as well as preliminary experimental results.   This work is a collaboration with an optical experimentalist Prof. Z. Chen in San Francesco State University.
