Abstract
Numerical studies on the soliton dynamics in passively mode-locked fiber ring lasers with dispersion-managed cavity have revealed the soliton period-doubling route to chaos, which confirmed our previous experimental observation of the phenomenon (Zhao L. M. et al., Opt. Expr., 12 (2004) 4573). In addition, our numerical simulations also verified that the period-doubling bifurcations and route to chaos are other intrinsic properties of the solitons in the lasers, which are caused by the deterministic dynamics of the system. Period-doubling of various periodic soliton states have been numerically obtained.
