Abstract
A device for modulation of light () having a wavelength, comprising: a first substrate () with a first face () and a second opposite face (), and comprising a first electrode (); a second substrate () adjacent to the second face () and defining a gap between the first and second substrate (), the second substrate () comprising a second electrode (); a responsive liquid crystal layer () disposed in the gap, wherein the responsive liquid crystal layer () has a flexoelectro-optic chiral nematic phase, and is birefringent with an optic axis that tilts in response to an applied electric field between the first and second electrode (); and a mirror adjacent to the second substrate (), the mirror configured to reflect incident circular polarised light while preserving its handedness.
