Higher-order Vector Soliton
In higher-order vector solitons, not only are the two orthogonally polarized soliton components phase-locked, but also one of the components has a double-humped intensity profile. Multiple such phase-locked high-order vector solitons with identical soliton parameters and harmonic mode-locking of the vector solitons have also been obtained in lasers. Numerical simulations confirmed the existence of stable high-order vector solitons in fiber lasers.
