Resonant delocalization and Bloch oscillations in modulated lattices

Opt Lett. 2011 Apr 15;36(8):1464-6. doi: 10.1364/OL.36.001464.

Abstract

We study the propagation of light in Bloch waveguide arrays exhibiting periodic coupling interactions. Intriguing wave packet revival patterns as well as beating Bloch oscillations are demonstrated. A new resonant delocalization phase transition is also predicted.
