Increasing demand for practical applications is forcing more in-depth research into optical vortices (OVs): from the generation and measurement to shaping multi-singularity manipulation of OVs. Herein, we propose a new type phase structure called high-order cross-phase (HOCP), which can be employed modulate OVs implement polygonal simultaneously at far-field. Theoretically, investigate propagation characteristics modulated by HOCP. In experiments, achieve via HOCPs. On this basis, discuss relationship between shapes orders HOCPs, where find that order HOCP exactly equal number sides This work provides novel method simultaneously, facilitate in micro-manipulation communication.
