Abstract: Methods of producing grating materials with variable height are provided. In one example, a method may include providing a grating material atop a substrate, and positioning a shadow mask between the grating material and an ion source, wherein the shadow mask is separated from the grating material by a distance. The method may further include etching the grating material using an ion beam passing through a set of openings of the shadow mask, wherein a first depth of a first portion of the grating material is different than a second depth of a second portion of the grating material.

Abstract: A method is provided. The method includes exposing a first material disposed across a first plane on a first substrate to an ion beam to form a first plurality of structures in the first material, the ion beam directed at the first material at an ion beam angle ϑ relative to a surface normal of the first substrate. The first substrate is positioned at a first rotation angle ϕ1 between the ion beam and a first vector of the first plurality of structures, the first material is exposed to the ion beam incrementally along a first direction, and exposure of the first material to the ion beam is varied along the first direction to generate a depth variation between the first plurality of structures in the first direction.
