Abstract: A fast and dynamic waveplate is described. The present systems and methods utilize stress birefringence that generates inside a plate when force is applied on one or more sides of the plate. The force is applied using one or more actuators distributed along the side(s) of the plate. The magnitude of the force can be controlled using a control unit. A generated stress birefringence is spatially varying across the plate. By carefully adjusting the force, the plate can be converted into a waveplate with an arbitrary value of retardance that is determined by the force. Since the parameter that determines the birefringence is force, a control unit can be used to apply different combinations of force values at a sub-millisecond speed to achieve fast control of the value of the birefringence as well as an orientation in the plate.
