Abstract
We address the properties of soliton propagation at the interface between media with uniform and chirped modulated nonlinearities. By changing the chirp parameter and modulation depth p of the nonlinearity, we can control the soliton propagation, including straight transmission, drift left, and drift right. In particular, the formation of a surface soliton does not need a power threshold. Thus, our results offer a new (to our knowledge) method to control the soliton propagation, which potentially applies to optical signal processing and optical switching.
