Propagation dynamics of controlled cross-talk via interplay between chi((1)) and chi((3)) processes
Additional Document Info
We investigate theoretically and experimentally the propagation dynamics of a nonlinear cross-talk effect between two probe channels in a double-ladder system and show that an interplay between (1) and ( 3) processes leads to the control of cross-talk. We derive analytical solutions to describe the propagation dynamics of the probe fields with the cross-talk effect built in. From the analytical results we identify and examine the regimes of interest where contributions of either (1) or (3) or both are significant. The control of cross-talk is demonstrated experimentally, and good quantitative agreement is found between the analytical solutions and the experiment. 2011 American Physical Society.
