In this paper, we combined spiral zone plates and gratings using a logical XOR operation, designing new optical element called the composited modified plate grating (CMSZPG), which can generate multiple focused vortices on same focal plane. The parameters of CMSZPG are optimized genetic algorithm, enables generation equal intensity vortex beams without complexity manual adjustments, thereby reducing workload. theoretical feasibility component has been validated through simulations experiments. beams, have potential applications in light trapping imaging fields.
