Transverse instability of vector solitons and generation of dipole arrays
Phys. Rev. Lett. 87, 103903 (2001)
Abstract:
We develop a theory of modulational instability of multi-parameter solitary
waves and analyze the transverse instability of composite (or vector)
optical solitons in a saturable nonlinear medium. We demonstrate theoretically
and experimentally that a two-component soliton stripe breaks-up into an array
of (2+1)-dimensional dipole-mode vector solitons, thus confirming a robust
nature of those solitons as fundamental composite structures of incoherently
coupled fields.
