    Abstract: A beam expander and a displays including the beam expander are provided. The beam expander includes a holographic optical element (HOE) configured to generate collimated light by diffracting incident light incident thereon from a light source that emits coherent light. The beam expander also includes a diffraction optical element that diffracts light received from the HOE. The light source and the HOE may face each other with the diffraction optical element therebetween. Both the light source and the HOE may be arranged on a side of the diffraction optical element. The light source may be arranged above or below the diffraction optical element.

    Abstract: Provided are a backlight unit and a holographic display apparatus including the same. The backlight unit includes a light guide plate; an input coupler configured to guide light into the light guide plate; a light deflector configured to deflect light emitted from the input coupler and guide the deflected light to propagate within the light guide plate. The light deflector is disposed on a region of the light guide plate which does not overlap with an optical path of light incident on the input coupler. The backlight unit also includes an output coupler configured to emit the light, having been propagated within the light guide plate, to an outside of the light guide plate.
