abstract = "To explore the effect of the incident polarization on achieving polarization-controllable multifocal arrays (MFAs), the polarization-controllable MFAs generated by radially polarized (RP) and azimuthally polarized (AP) beams are compared in this work. Four phase filters for the numerical aperture (NA) of 0.80, 0.85, 0.90 and 0.95 are respectively designed to generate the polarization-controllable MFAs under the illumination of RP and AP beams. The intensity comparison demonstrates that the polarization-controllable MFAs generated by AP beams have the higher uniformity, smaller focal spots and more stable intensity distributions for the same NA. The polarization comparison demonstrates that the polarization properties of the polarization-controllable MFAs generated by AP beams are more consistent with the desired target. Therefore, the AP incident beam is the better choice to realize a polarization-controllable MFA by a phase filter.",
