Stable higher-charge discrete vortices in hexagonal optical lattices Academic Article uri icon


  • We show that double-charge discrete optical vortices may be completely stable in hexagonal photonic lattices where single-charge vortices always exhibit dynamical instabilities. Even when unstable the double-charge vortices typically have a much weaker instability than the single-charge vortices, and thus their breakup occurs at longer propagation distances. 2009 The American Physical Society.
