    Abstract: Provided are a nanostructured optical element, a depth sensor, and an electronic device. The nanostructured optical element includes: an array of a plurality of laser sources; a meta-pattern layer including a two-dimensional array of plurality of first nano-posts; and a deflecting layer between the light source and the meta-pattern layer. Each of the first nano-posts has a dimension smaller than a wavelength of light output from the plurality of laser sources. The deflecting layer is configured to direct light from the light source onto the meta-pattern layer.

    Abstract: Provided are a nanostructured optical element, a depth sensor, and an electronic device. The nanostructured optical element includes: a light source in which a plurality of laser sources irradiating light are configured as an array; a meta-pattern layer including a plurality of first nano-posts that are two-dimensionally configured while satisfying a sub-wavelength condition, wherein the plurality of first nano-posts are configured to change the light from the light source into structured light; and a deflecting layer between the light source and the meta-pattern layer, and configured to change a proceeding direction of the light to make the light from the light source be incident to the meta-pattern layer.

    Abstract: Provided is an optical device including an active layer, which includes two outer barriers and a coupled quantum well between the two outer barriers. The coupled quantum well includes a first quantum well layer, a second quantum well layer, a third quantum well layer, a first coupling barrier between the first quantum well layer and the second quantum well layer, and a second coupling barrier between the second quantum well layer and the third quantum well layer. The second quantum well layer is between the first quantum well layer and the third quantum well layer. An energy band gap of the second quantum well layer is less than an energy band gap of the first quantum well layer, and an energy band gap of the third quantum well layer is equal to or less than the energy band gap of the second quantum well layer.

    Abstract: Provided are meta-surface optical device and methods of manufacturing the same. The meta-surface optical device may include a meta-surface arranged on a region of a substrate and a light control member arranged around the meta-surface. The light control member may be arranged on or below the substrate. A material layer formed of the same material used to form the meta-surface may be disposed between the light control member and the substrate. Also, the meta-surface may be a first meta-surface arranged on an upper surface of the substrate, and a second meta-surface may be arranged on a bottom surface of the substrate. Also, the meta-surface may include a first meta-surface and at least one second meta-surface may formed on the first meta-surface, and the light control member may be arranged around the at least one second meta-surface.
