A partially coherent off-axis double vortex beam (PCOADVB) composed of two off-axis vortices is theoretically presented. The analytical equations of a PCOADVB in oceanic turbulence are presented, and the intensity profiles and the number of coherence vortices of the PCOADVBs are investigated based on the derived expressions. The numerical results show that the intensity profiles of PCOADVBs are determined by the initial topological charges M1 and M2 and the positions of the off-axis vortices (x1d,y1d) and (x2d,y2d). The intensity profiles of PCOADVBs will lose the off-axis ring intensity profile and acquire a Gaussian-like profile as z increases, and stronger oceanic turbulence and a smaller σ can help the PCOADVB evolve into a spot with a Gaussian-like profile faster on propagation. The number of coherence vortices of a PCOADVB in oceanic turbulence will increase on propagation. The PCOADVB may have potential applications in underwater laser sensing and wireless communications.

“…In nonlinear media, such refractive index landscapes (in particular, periodic geometries) may support rich families of lattice solitons, which have been observed in multi-dimensional geometries [6][7][8][9][10][11][12]. Lattices may suppress azimuthal modulation instabilities, thus stabilizing vortex states (see reviews [13][14][15], experimental realizations [16][17][18][19][20] and theoretical proposals [9,[21][22][23][24][25], including in dissipative systems [26]). Vortices can also exist in structures exhibiting discrete angular rotational symmetry rather than transverse periodicity, such as modulated Bessel lattices [27][28][29][30][31] or photonic crystals [32].…”
