Abstract

In this paper, the transport properties of the autofocusing Airy vortex beams are investigated in the case of coexistence of positive and negative topological charges in the cross-section of the optical field. It is found that, unlike homogeneous vortex pairs, vortex pairs with opposite sign do not rotate the optical field during the transmission process, and that the autofocusing properties of the optical field can be modulated by a simple algebraic addition and subtraction operation of the topological charges. This study provides an important reference for the application of OAM-based communication systems and imaging systems in the atmosphere.
