We generate a new type of perfect optical vortex called the polygonal perfect optical vortex (PPOV) by combining the Bessel-Gauss beam with the high-order cross-phase (HOCP) at the plane of a spatial light modulator (SLM). This is the first time that the HOCP is applied to the Fourier plane of an optical field (POV) instead of directly acting on an optical field itself. Experimentally, the symmetrical PPOV is generated, and the capability of asymmetric distribution is demonstrated. Furthermore, we discuss the influence of parameters on a PPOV. On this basis, we show a novel function of the PPOV that can adjust the energy distribution at the vertices while maintaining the orbital angular momentum as much as possible, which facilitates applications in optical micro-manipulation.
