    Abstract: Embodiments described herein relate to flat optical devices and methods of forming flat optical devices. One embodiment includes a substrate having a first arrangement of a first plurality of pillars formed thereon. The first arrangement of the first plurality of pillars includes pillars having a height h and a lateral distance d, and a gap g corresponding to a distance between adjacent pillars of the first plurality of pillars. An aspect ratio of the gap g to the height h is between about 1:1 and about 1:20. A first encapsulation layer is disposed over the first arrangement of the first plurality of pillars. The first encapsulation layer has a refractive index of about 1.0 to about 1.5. The first encapsulation layer, the substrate, and each of the pillars of the first arrangement define a first space therebetween. The first space has a refractive index of about 1.0 to about 1.5.

    Abstract: Embodiments described herein provide for devices and methods of measuring a pitch P of optical device structures and an orientation angle ϕ of the optical device structures. One embodiment of the system includes an optical arm coupled to an arm actuator. The optical arm includes a light source. The light source emits a light path operable to be diffracted to the stage. The optical arm further includes a first beam splitter and a second beam splitter positioned in the light path. The first beam splitter directs the light path through a first lens and the second beam splitter directs the light path through a first dove prism and a second lens. The optical arm further includes a first detector operable to detect the light path from the first lens and second detector operable to detect the light path from the second lens.

    Abstract: The present disclosure generally relates to methods of forming optical devices comprising nanostructures disposed on transparent substrates. A first process of forming the nanostructures comprises depositing a first layer of a first material on a glass substrate, forming one or more trenches in the first layer, and depositing a second layer of a second material in the one or more holes to trenches a first alternating layer of alternating first portions of the first material and second portions of the second material. The first process is repeated one or more times to form additional alternating layers over the first alternating layer. Each first portion of each alternating layer is disposed in contact with and offset a distance from an adjacent first portion in adjacent alternating layers. A second process comprises removing either the first or the second portions from each alternating layer to form the plurality of nanostructures.
