We introduce a mechanism to stabilize spatiotemporal solitons in Kerr nonlinear media, based on the dispersion of
linear coupling between the field components forming the soliton states. Specifically, we consider solitons in a
two-core guiding structure with inter-core coupling dispersion (CD). We show that CD profoundly affects properties
of the solitons, causing the complete stabilization of the otherwise highly unstable spatiotemporal solitons in Kerr
media with focusing nonlinearity. We also find that the presence of CD stimulates the formation of bound states,
which, however, are unstable. |
