Optical element and method of manufacturing optical element with each of first and second layers having a repetition structure
First Claim
1. An optical element comprising:
- a substrate; and
a first layer formed on the substrate; and
a second layer formed on the first layer,wherein the first layer comprises a repetition structure of spaces and linear structural parts at a pitch equal to or less than a wavelength of visible light,wherein the second layer comprises a repetition structure of spaces and linear structural parts at a pitch equal to or less than a wavelength of visible light,wherein the linear structural parts of the second layer are formed so as to cross over the spaces of the first layer,wherein the linear structural parts of the first layer are elongated in a direction so as to contact multiple linear structural parts of the second layer, andwherein upper portions of the structural parts of the first layer and lower portions of the structural parts of the second layer engage into each other in a range of 3 nm or more and 20 nm or less.

Abstract
An optical element having a three-dimensional structure which can function in a visible range and can improve adherence at a structural interface of the element, and a method of manufacturing the optical element. The optical element includes a substrate, and at least a first layer and a second layer on the substrate are manufactured such that each of the first layer and the second layer has a repetition structure of spaces and structural parts at a pitch equal to or less than a wavelength of visible light, and at an interface between the first layer and the second layer, overlapped structures are provided in which the repetition structure of the first layer and the repetition structure of the second layer overlap in a stack direction of the layers.
