We show that the vortex-induced waveguide greatly improves conversion efficiency from the fundamental to the second-harmonic field.Keywords: Approximation theory; Asymptotic stability; Frequencies; Harmonic analysis; Light propagation; Nonlinear systems; Resonance; Second harmonic generation; Solitons; Vortex flow; Second-harmonic fields; Vortex-induced waveguides; Optical waveguides20042015-12-11
