Embodiment Construction

[0063] Reference will now be made in detail to the example embodiments shown in the drawings, wherein similar reference numerals refer to similar elements throughout the drawings. In this regard, the example embodiments may have different forms and should not be construed as being limited to the description set forth herein. Therefore, the exemplary embodiments are described below only by referring to the figures to explain various aspects. The term "and / or" as used herein includes any and all combinations of one or more of the related listed items. Expressions such as "at least one of" after a list of elements modify the entire list of elements, rather than modify individual elements in the list. For example, the expression "at least one of a, b, and c" should be understood to include only a, only b, only c, both a and b, both a and c, both b and c, or a, b and All of c.

[0064] Hereinafter, example embodiments will be described in detail with reference to the accompanying d...

Abstract

Provided is a meta-lens including a first region including a plurality of first nanostructures that are two-dimensionally provided in a circumferential direction and a radial direction, wherein the plurality of first nanostructures are provided based on a first rule, and a plurality of second regions surrounding the first region, each of the plurality of second regions including a plurality of second nanostructures that are two-dimensionally provided in a circumferential direction and a radial direction, wherein the plurality of second nanostructures are provided in each of the plurality of second regions based on a plurality of second rules, respectively, that are different from the first rule.

Description

[0001] This application requires the rights and interests of U.S. Provisional Application No. 62 / 774,562 filed in the U.S. Patent Office on December 3, 2018 and Korean Patent Application No. 10-2019-0046940 filed in the Korean Intellectual Property Office on April 22, 2019. Priority, the entire disclosure of which is incorporated herein by reference. Technical field [0002] Example embodiments of the present disclosure relate to a super lens and an optical device including the super lens. Background technique [0003] Optical sensors using semiconductor-based sensor arrangements are increasingly used in mobile devices, wearable devices, and the Internet of Things. [0004] Despite the need to miniaturize such devices, it is difficult to reduce the thickness of the optical lens included in the device. In a lens that controls optical performance by using curvature, the refractive power increases as the radius of curvature decreases, because as the radius of curvature decreases, the ...
