Optical vortex lattices are fundamental to advancing high-capacity spatial multiplexing and multiparticle manipulation. However, transporting these complex arrays over extended free-space distances remains a challenge, as natural transverse diffraction inevitably triggers intense coherent crosstalk that degrades predefined topological structures. Here, we demonstrate a multiparameter modulation strategy that mitigates this propagation constraint through initial-phase engineering. By introducing a designed optical-axis offset between adjacent lattice cells, the resulting field acquires a controlled phase relation that promotes localized destructive interference, forming a dark grid that reduces transverse overlap and coherent intercell coupling. This mechanism is experimentally realized through liquid-crystal photoalignment, achieving an array-generation efficiency of up to 90% without the pixelation-induced zero-order background associated with conventional spatial light modulator implementations. Under this collective transverse confinement, the generated scalar vortex-antivortex and conjugate vectorial vortex lattices preserve information-bearing central vortex units over extended propagation distances. Their phase singularities remain identifiable throughout the structured local-field evolution, and the conjugate vectorial vortex lattice retains a discernible alternating polarization organization. Following a localized obstruction, the vectorial lattice recovers the phase- and polarization-encoded organization of its central region. This geometric phase platform is electrically tunable and scalable to higher-order topological states such as optical skyrmions, offering a reliable hardware architecture for advanced structured light applications.
