Abstract: A controllable light propagation system includes a light guide elongated in a first direction, a controllable liquid crystal (LC) element including an LC material and having a first side adjacent the light guide to define a dynamic interface between the light guide and controllable LC element, and an array of electrodes arranged at different locations along the first direction. The array of electrodes arranged along the first direction are selectively activatable to generate electric fields in the LC material to control a transmissivity of the dynamic interface between the light guide and the controllable LC element, thereby allowing a controlled extraction of light at selected locations along the light guide. An array of optical elements may be provided at a second side of the controllable LC element to deflect or otherwise influence the extracted light, e.g., as a function of the location of the extracted light along the first direction.
