Abstract: Embodiments described herein provide for methods of forming optical device structures. The methods utilize rotation of a substrate, to have the optical device structures formed thereon, and tunability of etch rates of a patterned resist disposed over the substrate and one of a device layer or the substrate to form the optical device structures without multiple lithographic patterning steps and angled etch steps.
