  Cylindrical vector beams (CVBs), which possesses polarization distribution of
rotational symmetry on the transverse plane, can be developed in many optical
technologies. Conventional methods to generate CVBs contain redundant
interferometers or need to switch among diverse elements, thus being
inconvenient in applications containing multiple CVBs. Here we provide a
passive polarization-selective device to substitute interferometers and
simplify generation setup. It is accomplished by reversing topological charges
of orbital angular momentum based on polarization-selective Gouy phase. In the
process, tunable input light is the only condition to generate CVB with
arbitrary topological charges. To cover both azimuthal and radial parameters of
CVBs, we express the mapping between scalar Laguerre-Gaussian light on basic
Poincar\'e sphere and CVB on high-order Poincar\'e sphere. The proposed device
simplifies the generation of CVBs enormously, and thus has potentials in
integrated devices for both quantum and classic optical experiments.
