Switching and instabilities of optical vortices in nonlinear dual-core photonic crystal fibre couplers
Abstract
dual-core waveguide coupler in a photonic crystal fibre with
self-focusing nonlinearity. We analyse how the beam power and the
angular momentum associated with the vortex mode transfer to the
second core of the coupler in both linear and nonlinear regimes. We
describe three major scenarios of the vortex dynamics and reveal
novel symmetry-breaking instabilities associated with the vortex
nonzero angular momentum.
