Abstract: I will present a theory of coherent light propagation and energy transfer in a multicore 
optical fiber with nonlinear and linearly coupled cores. It is demonstrated that in the optical fiber 
with a central core and N periphery cores stable steady-state coherent multicore propagation is 
possible only for the vortex structures. Analytical and numerical results on the existence, stability 
and dynamical behavior of the vortex structures will be discussed. The presented theory of energy 
transfer in nonlinear discrete systems is rather generic and has a range of potential applications 
including both high-power fiber lasers and ultrahigh-capacity optical communication systems.
