摘要
In the past years, enhanced techniques to tailor amplitude, polarization and phase have established the generation of singularities in all degrees of freedom, as phase or polarization vortex structures and caustics [1] . Structured polarization and phase singularities can have an integer, quantized nature which connects structured light to quantum physics and is likely to improve security in data communication [2] . In optical micromanipulation, the spin and orbital angular momentum of light, defined by its polarization and phase structure, enable the transfer of torque to optically trapped particles [3] , providing additional degrees of freedom to advance optical tweezers [4] .
