Realization of the spin-dependent manipulation of structured light by tailoring the polarization

Here, we review our recent works about the realization of the spin-dependent manipulation of structured light by tailoring the polarization. We develop a theory for spin-dependent manipulation based on the polarization design. As the exemplary demonstration, our experimental results show that such a theory can attain the spin-dependent splitting, and spindependent diffraction. Furthermore, we demonstrate this theory can be also applied to the spindependent focusing. The scheme provides a possible route for the manipulation of spin states of photons, and enables spin-photonics applications.
