In terms of system integration and device miniaturization, a single optical that can possess more tunable functionalities in multiple channels is desirable. As proof concept, we experimentally demonstrate such an ultrathin simultaneously realize polarization-controllable hologram superposition orbital angular momentum (OAM) channels. By continuously controlling the polarization state incident light, polarization-dependent holographic images two along horizontal direction continuous control OAM vertical are realized. The uniqueness lies both superpositions states controlled at same time. This novel provides fast efficient tool for simultaneous manipulation supposition various channels, which significantly simplifies experimental importance current efforts field information optics, security, quantum science fundamental physics.
