An optical device includes a first electrode and a medium that includes ferroelectric liquid crystals and chiral dopants. The medium is located adjacent to the first electrode. The optical device may also include a second electrode distinct and separate from the first electrode. The optical device may be used as an optical dimming device, controlling an amount light passing through the optical device based on a voltage gradient provided to the optical device.

Optical dimming devices with chiral ferroelectric nematic liquid crystal

An optical device includes a first set of one or more electrodes, a second set of one or more electrodes distinct and separate from the first set of one or more electrodes, and a medium that includes liquid crystal physical gel. The medium is located between the first set of one or more electrodes and the second set of one or more electrodes. The optical device may operate as an optical dimming device, which may be used in head-mounted display devices or as dimmable windows or shutters.
