Optically Switchable Circularly Polarization-Dependent Optical Vortex

Optically Switchable Circularly Polarization-Dependent Optical Vortex

An optical vortex, which consists of blue phase and isotropic phase, is generated from azobenzene liquid crystal cell with computer generated hologram pattern. This device is optically switchable and can be erased and generated by ultraviolet or green light, respectively. An intensity modulation is...
