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.
