Abstract:
A dynamically programmable, nonlinear beam-shaping and steering system is demonstrated, based on photopatterned, electrically controlled, ion-doped liquid ferroelectrics. This innovative approach elevates the linear liquid-crystal Pancharatnam-Berry optics to the reconfigurable nonlinear Pancharatnam-Berry optics regime, creating new possibilities for dynamic light-matter interactions, multiplexing holography, tunable quantum optics, and many other reconfigurable photonic applications.
