Abstract: An optical thin film includes a support layer and a dielectric layer on the support layer. The dielectric layer has a refractive index greater than that of the support layer. The dielectric layer includes a compound ADX, which includes a Group 3 element A, a Group 5 element D, and an element X having an atomic weight smaller than an atomic weight of A or D. The optical thin film may exhibit light transmission having a high refractive index and low absorptivity.

Abstract: A method of evaluating the quality of a thin film layer may include: forming the thin film layer on a substrate; applying a stress to the thin film layer; and evaluating the quality of the thin film layer. A device for evaluating the quality of the thin film layer may include a stress chamber for applying a stress to the thin film layer and a refractive index measuring unit for evaluating the quality of the thin film layer based on a rate of change of a refractive index.

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.
