    Abstract: A meta-lens, an imaging optics, and an electronic device including the imaging optics are provided. The meta-lens includes at least one meta-layer having a plurality of nanostructures with a less shape dimension than an operating wavelength, modulates a phase and intensity of incident light, and forms a plurality of spots of different brightness on an imaging plane in an asymmetric distribution. The plurality of spots formed on the imaging plane include a main spot and at least one sub-spot that is separated from a center of the main spot and has lower illuminance than the main spot.
